How to keep weeds from growing between pavers
There’ s nothing more frustrating than having weeds growing between the joints of pavers. Before you know it, the weeds can take over and be almost impossible to remove.
I’m going to share with you a step-by-step way to remove the weeds between pavers, but before I do I want to talk about how the weeds got there in the first place.
How do pavers get weeds in the first place
In my years, I’ve heard many explanations of where the weeds come from. In most cases, they were wrong.
The #1 misconception is that the weeds come from beneath the pavers. People that believe this, will ask us to install a weed mat beneath the pavers prior to installing them. However, this is not where the weeds come from and this certainly is not how you keep weeds from growing between your pavers.
99% of the time, weeds in pavers start from seeds blown in from weeds that are around the patio. Chances are, if you have lots of weeds in your pavers you probably also have lots of weeds in your yard. If you don’t believe me, see how Colorado State University says weeds start growing.
If your lawn is free of weeds, the seeds could be blowing in from your friendly neighbors yard. Once you have a couple weeds in your patio, they will start to spread. Some types of weeds like crabgrass can spread and take over your entire patio.
How to get ride of weeds in pavers
Before I share how we remove weeds from pavers, I want you to know that a properly installed paver patio will not grow weeds near as easily and if you follow the “How to keep weeds from growing between pavers” instructions at the bottom of this article, your patio wont grow weeds either.
I also wanted to note that weeds love a cool, damp environment. If your patio doesn’t have adequate slope to drain the water off the patio when it rains, chances are the sand in the joints will remain damp making them a thriving place for weeds to germinate and grow. If this is you, you’ll definitely want to get our “How to keep weeds from growing between pavers” instruction manual.
Step 1: Kill the weeds
There are many ways that you can kill the weeds between pavers. Bleach and Round-Up are a couple options, but we don’t like either of them for multiple reasons. They both are harmful to the environment, and the bleach can discolor the pavers. The solution, white vinegar. Crazy, I know.
You’ll first want to do a test spot just to make sure the vinegar doesn’t discolor the pavers. Vinegar does have a small amount of acid, however, it’s usually not enough to affect the pavers. I still recommend that you do a test spot.
To do your test spot, spray the vinegar in a 2’x2′ area of your pavers. Wait a couple hours, then rinse off the pavers. If you don’t see any discoloration, you’re good to go.
We recommend using a pump up weed sprayer for larger projects. Empty the white vinegar into your sprayer and spray the weeds. Let it sit for a couple hours. Then rinse away.
Step 2: Remove the dead weeds
We remove the weeds by using a pressure washer. Typically, when we’re removing weeds from pavers for a client, we’re also looking to clean the pavers. A Pressure washer is great for doing both. We use both a spray wand and also a rotating surface cleaner attachment for the pressure washer. Both of these can be rented from most tool rental stores for less than a $100 per day.
Here is rotating surface cleaner attachment for pressure washers.
If your project is a larger area, you can save yourself a lot of time and achieve a better end result by utilizing one of these. However, you may still need to use the regular pressure washer wand to remove stubborn dead weeds from the pavers. The rotating surface cleaner does an amazing job at cleaning the pavers also.
You will NOT want to use the jet nozzle of the pressure washer as this can etch and cut grooves into your pavers. Instead, use one of the fan nozzles. Hold the nozzle about 12″ away from the pavers focusing on the joint. You’ll goal is to spray out the weed from the joint. If your joint is full of silt/dirt, you can also go ahead and blast that out.
Warning: Your pavers are setting on a bed of sand. If you’re not careful, you can blast the sand from beneath the pavers right out the joint. Once the weeds are gone from the joint, be sure to move on to the next one.
Keep the weeds from coming back
After you’ve invested all this time an energy in removing the weeds from your pavers, the last thing you want the weeds to do is return. The problem: unless you do anything about it, they will. We’ve developed a step-by-step system that you’ll want to do right after you finish removing the weeds from the pavers to keep the weeds from coming back. In addition, this process will enhance the look of your pavers almost making them look new again.
We charge our customers about $2 per square foot of pavers for this service, however, if you’re not located in our service area (Southern Ohio), we would be happy to share this process with you – which will save you hundreds. We just ask that you pay us a small fee for the time we’ve invested putting this together. In addition, we will be happy to answer any technical questions that you have after you’ve purchased the step-by-step program.

Hi Mark – we ordered your instructions on fixing and sealing our patio brick pavers. Our patio is 17 years old and needed some help. We just finished our project and although not professionals, we can’t believe how great it looks. Our pavers sparkle in the sunlight and the sand in the seams is rock hard. Your process couldn’t be easier and even though contractors around here said we should us that other sand that hardens, we read too many bad reviews about it. Dont have a before picture but it truly wasn’t pretty – lots of gaps, moss and weeds from chipmunk damage. Thanks so much for sharing your method. Here’s a picture.

I’m not a professional, will I be able to follow your instructions?
Absolutely. We’ve written the instructions in a way that anyone can understand and follow regardless of experience level.
Will I need any tools?
You’ll more than likely have most of the necessary tools (there aren’t many required). Chances are that if you don’t, you’ll know someone who does. Like a neighbor. Any tools that you don’t have, you’ll be able to rent from your local Home Depot or tool rental facility and still save a bundle over hiring a company to do this for you.
My pavers are new, will this process still work?
For sure. In fact, it’s much easier for newer pavers (usually requires less cleaning)
My pavers are old, will this still work?
Although the instructions can be followed for new pavers, they’re written and intended for old, dirty pavers that have weeds that won’t stay away.
But polymeric sand makes the sand hard so that weeds can’t grow and sand doesn’t spread everywhere.
You’ll get the same results from our process that you will with polymeric sand. I.e. the sand hardens. However, our process will last much longer and has many other crucial benefits for not only keeping the weeds out but also keeping your pavers clean.
Does your process require that I purchase any products?
Yes it does, and we’ll tell you exactly what to buy. It will only cost you about $35 per 100 square feet of paver area. Again, you’ll still save hundreds over hiring this out.
How long will it take?
Of course it depends on how big your paver area is, but the average paver patio is about 300-400 sq feet. Based on the average patio size, expect to spend about 6-8 hours spread over two days. Probably less time than you spend every year cleaning and pulling weeds from your pavers now.
How/When will I receive the instructions?
We’ll email them to you within 24 hours after you make the payment, but in most cases you’ll have them in an hour or two during daytime hours. We’ll get your email during the checkout process.
My pavers are very dirty, is it worth it?
Our instructions will show you how to deep clean your pavers making them look amazing again.

I’m Mark, the owner of Two Brothers Brick Paving. Thanks for taking a second to read this article. I strongly feel that if I educate my customers about me, my company and hardscapes, in the end they will be a happier customer. I have three awesome boys named Wes, Greyson and Braxton. My wife Katie and my family are my motivation to be the best I can be and that shows in my work. I’ve been in this industry most of my life and prior to starting my own company I worked for one of the largest/best installers in the country (it was actually the first contractor to install an interlocking concrete paver). I can bring a tremendous amount of knowledge and expertise to your project.
- Boiling water: If the unwanted grass is near the kitchen door, pour leftover boiling water from the stove on weeds rather than down the drain. Do not worry if there is salt in the water; salt helps kill many weeds. Make sure you do not use water that has oils or meat leftovers from cooking. After a few boiling water treatments, most broadleaf weeds and grasses give up.
- Kitchen vinegar concoction: A mixture of 1 cup salt (about 228 grams) and one gallon (about 3.8 liters) of white vinegar (5 percent acetic acid) on hardscape will kill most weeds and grasses. To make it even more caustic, add 1 cup (about .28 liters) of lemon juice. To increase sticking power, add 2 tablespoons (about 28 grams) of dish soap. If you have it, pickling vinegar is more acidic than regular white vinegar and probably more effective.
- Propane torch: An ordinary propane torch can be used to burn weeds sprouting up through pavement cracks. Many weeds tolerate a fair amount of heat, but not the 2,000 degrees produced by a propane flame. Some manufacturers now offer long-handled weed torch tools specifically for this purpose.
- Horticultural vinegar: It may be hard to find in local stores, but it can be ordered online. This vinegar is 20 percent acetic acid. Mix it with some orange oil and a bit of phosphate-free dish soap. Acetic acid burns the plant’s top growth, depriving it of the ability to photosynthesize. Make sure you use protection for your hands and eyes, it is acidic and can burn you.
- Non-selective weed killer: Chemicals should be a last resort, but if other methods fail, spot-treating grasses and weeds with a weed-killer containing glyphosate (such as Roundup) will kill the plant, roots and all. Any chemical product should be used carefully, but glyphosate does not linger in the environment the way the chemicals in some other weedkillers do. Note that most weed killers will not kill grasses only broadleaf weeds.
- Seal cracks: Plants cannot sprout up if there are no cracks for seeds to penetrate. Inspect your pavement annually and fill any cracks with mortar or a mortar caulking product. Vacuum out the cracks first, then fill them with mortar or masonry caulk to seal them.
How to Stop Weeds from Growing Between Pavers
A deck or patio crafted of pavers is sure to have lines between each stone. Without proper prevention, weeds can find their way through those joints, reducing the appearance and potentially causing damage to the entire floor. With a few preventative measures, weeds can be avoided in the first place. If weeds are already present, there’s no need to stress. Corrective measures can eliminate the weeds and restore the look of your driveway, deck, or patio.
Preventing Weed Growth
Prevention is one of the best methods of weed control. With a little regular maintenance, weeds can be avoided in the first place.
Most of the time, weeds to not sprout up from beneath the pavers. They actually start with seeds that settle between the cracks of the pavers on the surface. Seeds need to take root in order to grow. Sweeping your pavers regularly will disrupt the seeds prior to rooting, helping to inhibit weed growth. Sweeping also removes surface dirt and helps to enhance curb appeal by keeping your pavers looking clean.
Installing pavers results in spaces between the bricks or stones. The first step in preventing weeds is ensuring proper installation. A sand bed tightly packed provides a level foundation for the deck or patio. Once all the pavers are in place, additional sands should be packed into the crevices. This sand ensures each paver stays in place and helps prevent weed growth.
Ensure Proper Slope
Weeds thrive in cool, damp soil. When the deck or patio is properly sloped, water runs down the slope and doesn’t stay stagnant in the crevices between the pavers, helping to prevent the conditions weeds need to thrive. The slope of the paved area should always tilt away from the house.
Is It Too Late?
When weeds are already present you have to go from prevention to finding effective remedies for the problem. There are a number of ways you can remove existing weeds from your paver area. A single weed-removal method may not be enough. It may be more effective to combine two or more of these strategies, depending on how severe the weed problem is. Once the problem has been rectified, go back to the prevention methods to keep them away.
Instead of treating weeds with harsh chemicals, open the pantry and reach for the white vinegar. Pour the vinegar into an empty spray bottle and spray the cracks between the pavers, leaving it to sit and work its way into the sand. When a few hours have passed, rinse away the vinegar with a garden hose. This simple remedy will kill the weeds without damaging the pavers or damaging nearby plants. Vinegar should not discolor pavers but if you have any concerns, do the same process with an inconspicuous test spot before treating the entire area.
Pressure washing the whole patio is a dual-purpose solution. Not only will it remove the weeds from the spaces between the pavers, but it will also provide a deep cleaning to the pavers, making the whole area look like new again. If you are pressure washing, do not simply use a jet nozzle. The water pressure from the nozzle can wash away the sand between the grooves and etch the surface of the pavers themselves. Instead, use a rotating surface cleaner attachment in tandem with the pressure washer.
Pulling weeds is a classic method of removal but it is only effective if the entire plant is removed, root and all. To do this, reach for the lowest point of the stem and carefully pull the weed. Any roots that don’t come with the plant will grow back. This often results in multiple hand-pulling sessions before the problem is remedied. Hands-on removal is possible at the onset of a weed problem, when only a few weeds are present, but it can become a very labor-intensive and less effective method when there is a severe weed problem.
An alternative to hand-pulling weeds is taking advantage of a mechanical removal solution. Crack scrapers are outfitted with L-shaped blades that pull a weed from the stem, removing the weed at the base of the stem. Normally, this method leaves behind the root, allowing for regrowth. As a result, mechanical removal is a way to temporarily restore the look of the deck or patio, but future mechanical removal sessions will be needed to remove regrowth.
Once you remove the weeds through one of the methods mentioned above, stabilizing sand can be used to help keep any roots from growing back. When adding sand, it is essential that the patio is dry and free of weeds. Some paver sands feature gel additives that react with water, filling in the space between the stones so weeds have nowhere to go. Some sands also feature a pH that inhibits weed growth by making it uninhabitable. The type of sand used will help to determine the proper installation method. Follow the instructions carefully to ensure the product is used properly.
Patio pavers bring a traditional elegance to the exterior hardscapes of any business or residence. Nothing will detract from the beauty of the pavers faster than the growth of weeds. When no weeds are present, simple preventative methods will help to keep them from growing. If weeds are already a problem, there are a number of methods that will eliminate the weeds. Discovering the best weed prevention and remedy for your paver area is easy when you understand what causes weeds in the first place and the pros and cons of each weed control method. A weed-free paver area is possible and goes a long way toward making a space inviting and enhancing the curb appeal of your home.

Rock Salt Used as a Weed Killer
A short while back, we had a customer at our Newbury depot making a purchase of Rock Salt which ordinarily is used in cold conditions and in the winter to combat the icy conditions associated with these times.
This admittedly had us confused as the weather was neither cold nor icy, in fact it was the exact opposite.
Normally, Rock salt finds itself being sprinkled on roads, drive and walkways before or after frost and snowfall however this customer seemingly was aware of a weed killing trick that we had missed.
Due to the amount of intrigue, some research had to be done into this and to our delight, we found some instructions on how to use Rock Salt as a weed killer which had to be shared. This is what we found:
- Sprinkle a few chunks of rock salt on the soil surface at the bases of weeds. They’ll begin dying from desiccation within several days. Use salt sparingly, and don’t count on anything growing there or in the area immediately surrounding it for years to come. Salt leaches into the groundand essentially sterilizes it, preventing vegetative re-growth.
- Spread a thin layer of rock salt between your walkway’s bricks, pavers or stones. It will kill any weeds or grass growing there, and keep them away for years.
- Apply rock salt to cracks and crevices in your pavement or driveway. Spread it over gravel walks and drives. It will remain active and prevent re-infestation for quite some time.
- Add 1 cup of rock salt to 1 gallon of hot water. Stir until the salt is dissolved. Pour the herbicide into a plastic spray bottle. Apply to crabgrass and broadleaf weeds. Reapply five days later. Complete the treatment with a third application five days after that
As we found out, there are quite a few ways of applying Rock Salt to the weed effected areas and from what it seems, it provides a very effective and quite frankly cheaper alternative to the mainstream weed killing methods.
So when the winter time comes around, it might be worth keeping a bit of spare Rock Salt ready to reenact your very own Rambo scene on those weeds.
However if you would like to hasten this, what seems like a forever on-going battle, you can purchase Rock Salt from Rivar Sand and Gravel.
5 Ways to Prevent Weed Growth Between Paving Stones
Oops! Weeds between Pavers
So, you have installed your patio paving using the high-quality natural stone pavers looking gorgeous. Now, one year has passed, and it started getting dreadful due to unwanted growth of weeds. You might wonder how weeds emerged instantaneously in your garden paths, patio pavers, or driveways. If you have a look closely to your stone-brick patio, which has crevice in between the pieces and growth of grass between pavers./
Of course, these crevices are responsible for the formation of simple to fascinating designs at one hand. The same also become the cause of harboring notorious weeds infestations. Dispersion of weeds may take place through any route, but seeds are certainly coming from your vicinity, be it your garden or from the neighborhood and resulting as grass between pavers.
Unfortunately, we are helpless to stop the dispersion of seeds of weeds, but certainly can stop its growth and remove sprouted seeds or already grown weeds.
Natural Stone Pavers Collection
Let’s See How to Stop Weeds From Growing Between Pavers
The first thing should first. You have to remove the already grown weeds first and think of its preventions later. Let’s get some good clues to know that how to stop weeds from growing in your stone-brick patio or driveways.
1. Removing Weeds Manually or by Weed Pickers/Removers
It is true that picking weeds by hands demands exhaustive endeavors and some investment of tools. You have to wear the hand/garden gloves. It is because you have to work with damp soil. Dampening of soil is essential to ease the picking the weed plants right from the roots and pool those up easily.
You must follow the tips given below to know how to remove weeds.
|Select tight fitting garden gloves to get a good grip. Garden gloves save your hands from being dirty by wetted soil and hazardous living organisms residing in the damp soil.|
|Select comfortable knee pads to wear because you have to bend down for longer, and knee pads will save you from being dirty your clothes as well as any injury or insect bite.|
|Keep a moving trolley or dustbin to collect the weed along with picking up the process, so you have enough resting period in between the monotonous picking process.|
|Use billhook or crack-weeder for wider cracks and a serrated kitchen knife for narrow cracks to pull up weeds right from the roots.|
2. Killing Weeds by Applying Natural Remedies to Stop Weed Growth between Paving Stones
If you prefer green/environmentally safe ways to remove weeds from your backyard or garden patio, to follow are time-tested natural remedies those work at far cheaper rates. For instance, baking soda weed killer is one of those.
Using Backing Soda Weed Killer to Dry Out Stone-Brick Patio Weeds:
|Baking soda is chemically known as Sodium Bicarbonate. Technically, it overloads weed with salts and absorbs cellular water from the tissues of weed. Eventually, roots of weed dry out, and it dies. The baking soda weed killer is excellent choice due to instant availability.|
Apply Vinegar to Dry Out Patio Weeds:
|Vinegar, just like Baking Soda is chemically acetic acid. Technically, it draws the moisture out of the plant tissues including roots and leads the plant to death within a day or two.|
Use Common Salt to Kill Patio Weeds:
|Common Salt is chemically Sodium Chloride. When it used as oversaturated solution in 3:1 (Salt-:-Water) ratio, it dehydrates any plant including weeds of your pavers. Repeat the process monthly until new sprouting of weeds stops.|
Pour Boiling Water to Kill Patio Weeds:
|It is extremely inexpensive and simple way to kill the weed plants growing in cracks of the patio paving or garden paths. The best way is to apply grass cutter machine before boiling water treatment. It will open up the crown of the weed plants and provide space to hot drip water into the deep soil.|
3. Burn Weeds with a Weed Torch/Blowtorch to Prevent Weed Growth
|Using fire flames to burn the weed plants is an instant remedy for centuries. It demands extreme precautions when applied in an open space. Avoid usage near storage area, wooden parts of building, useful plants in nearby, and keep your clothes, kids, and other dry plants away while using it.|

4. Apply Chemical Treatment to Kill & Stop Growth of Weeds between Paving Stones
Today, many herbicides or weedicides available in the market, which are safe to apply at different stages of weed growth. For example, pre and post emergence stages of weed growth.
Pre-emergent weedicides are preventing the sprouting/germination of seeds of various weeds hidden in between the soil of patio stone cracks. It kills the key enzymes causing sprouting in seeds.
Post-germination weedicides are killing the weed plants right after the germinating or any stage of their lifecycle when applied in right concentration. Most of the post-sprouting herbicides acting on a specific genre of weed plants.
Selective Type of Herbicide
Selective types of herbicides act on the only specific genre of weed plants. It inhibits the sprouting of seeds at the pre-emergent stage. Similarly, it kills the weeds at the post-emergent stage.
Non-Selective Type of Herbicide
Nonselective types of herbicide can kill any plant, whether it is a weed or useful plant in your garden grown nearby your patio pavement or path. Therefore, use it carefully for stone or brick patios, sidewalk, and driveways including grass driveway pavers.
Contact Poison Type of Herbicide
As its name suggests, it acts only when it comes into the contact of any part of weed plant. It kills weeds immediately and dangerous while spraying in a residential area where the wind blows high or kids are playing around brick patio.
Systemic Poison Type of Herbicide
As its name suggests, it absorbed by the weed plants when spraying on any parts or tissues of the plant. It is dispersing in the entire internal system of the plant including roots, stems, branches, and leaves and disturb the key enzymatic processes within the plant and kill it gradually. It is completely safe when applied carefully in residential areas, including stone-brick patio.
5. Apply Polymeric Sand to Stop the Growth of Weeds between Paving Stones
In the old days, patio owners were removing old contaminated sands from cracks & sand between pavers in patio or bricks of brick patio. They used to fill up the crevices in stone pavers or brick patio with new or fresh sands between pavers.
Unfortunately, it alleviated weed growth only for limited period or seasons. It proves expensive when carried out frequently within a short span. It also loose the bonds of the structure of stone-brick patio due to frequent operations.
Fortunately, today we have the latest technologies called artificial sand granules made from polymeric chemicals. It binds or glues the sand particles after activation by water. Upon drying, it gets hard and cements the stones in pavers or bricks in brick patio to prevent invasion of seeds of weeds.
The prevention mechanism of polymeric sand is as follows.
EnviroSand is a known brand in polymeric sand manufacturers. It has plant glue, which converts into a gel when wetted with water. The gel prevents washout of sands and acts as the first line of defense to stop weed growth. It also has high pH, which ultimately inhibits future growth of seeds and plant sprouts in sand between pavers of stone-brick patio & grass driveway pavers.

How To Permanently Kill Weeds On Your Driveway
Weeds: The plants that refuse to die?
Sometimes the fight against weeds can seem futile. We might spend all afternoon on our knees ridding our driveways, paths, and patios of them; only for more weeds to reappear almost instantly. People can spend thousands with top driveway builders one year and then forget about the upkeep which can be a chore.
In this article, we’re going to look at ways to permanently kill off weeds from hard surfaces including:
- Concrete and stamped concrete
- Block paving
- Resin surfaces
What are Weeds?
A weed is any plant that grows where it’s not wanted: in the cracks between block paving, on gravel paths or drives, in gutters, etc.
There are many different types of weed, but things they all have in common include:
- Abundant reproduction
- Rapid establishment and spread
- The ability to spread in areas disturbed by human activity
- Seeds which can lay dormant for long periods of time
In other words, weeds do everything we don’t want them to do!
Why do weeds grow?
Weeds grow because they can, simple as that. Given the right condition for weeds to grow, nature will take its course no matter how much we’ve spent on our driveways or gardens.
Which weeds are most common on hard surfaces?
Some of the most commonly found weeds on hard surfaces include dandelions, plantain, meadow grass, couch grass, and the dreaded Japanese knotweed.
Unfortunately, most of these weeds are tough to kill and are perennial, meaning they can survive all year round.
What Weeds Are: Key Takeaways
- Weeds are any plants that grow where they’re not wanted
- Weeds will grow and spread wherever they can
- Most weeds on hard surfaces can survive in all conditions
How to Kill Weeds Permanently on Hard Surfaces
There are two approaches to tackling weeds. Killing weeds that are already there and preventing weeds from growing in the first place.
Although prevention is better than cure, you may be looking for a way to permanently kill existing weeds. With that in mind, we’re going to look at ways to both prevent and cure weeds.
How to Kill Weeds Permanently on Concrete Surfaces
Examples: Weeds on driveways and paths; stamped concrete surfaces
The bad news is that if your concrete surface has cracked or chipped and weeds have got through, you may not be able to kill them permanently to get rid of them.
Prevention: When laying a new concrete surface, lay two sheets of weed control or landscape fabric underneath. These will stop weeds from growing through the concrete.
Weeds thrive in damp conditions. Making sure your driveway is sloped enough to allow rain to drain away can help deprive weeds of the opportunity to root.
Cure: If weeds have grown through the concrete, then it’s a case of pulling them up as and when (being sure to get as much of the weed root as possible), and treating the area with a commercial weed killer. If you’ve got pets or are worried about environmental damage, boiling water or vinegar can also kill weeds.
You may also be able to reseal parts of the surface with a DIY concrete repair kit.
How to Kill Weeds Permanently on Paved Surfaces
Examples: Weeds on driveways, paths, gardens, and patios.
Prevention: At some point, it’s likely that weeds will appear in the cracks on a paved surface. These weeds aren’t growing up from beneath the surface. Instead, they’re growing from seeds that have blown into the sand used to fill the gaps between paving stones. As dirt also accumulates in the gaps, so weeds will flourish.
This means that, apart from making sure there is weed control fabric beneath your paving, the only prevention is to maintain your paving. You can do this by regularly brushing and washing it, using a sealant or launching a pre-emptive strike by using weed killer.
Cure: Once weeds have appeared in your paving, you can easily remove them manually. This can be done by hand or by using a special weeding tool for paving. You might also kill the weed first by pouring boiling water over them, spraying weed killer or using a flame gun.
To stop weeds coming back in a hurry, the next step is to clean the surface with a pressure washer. This will remove the gunk from between the slabs and also some of the sand. The gaps can then be refilled with fresh paving sand.
How to Kill Weeds Permanently on Gravel Surfaces
Examples: Weeds on driveways, paths, sections of gardens
Prevention: With gravel surfaces, even thorough prevention won’t guarantee freedom from weeds. Over time, the pressure of people walking and driving on it will cause pieces of gravel to pierce the weed control fabric, allowing weeds to grow through.
The most comprehensive weed prevention measure, in this case, is to replace the weed control fabric every couple of years.
Even then the surface is still susceptible to airborne seeds which can settle amongst the gravel and begin the weed growing process. The best prevention for this is to regularly rake your gravel. This will disturb any dirt and kill seeds, making it harder for weeds to establish themselves.
Cure: If weeds are growing from below then it’s very difficult to remove the root without further splitting the fabric. The best method is to use a specific weeding tool such as a corkscrew weeder.
Weeds can also be killed with weed killer, boiling water, vinegar or salt (note: salt is okay for hard surfaces but very bad for soil). Ultimately, however, a deteriorating fabric will have to be replaced.
If weeds have rooted above the fabric, they can be killed by any of the methods described above and removed by hand.
How to Kill Weeds Permanently on Resin Surfaces
Examples: Weeds on driveways, paths, patios, terraces
Prevention: Resin surfaces pride themselves on being weed resistant. Laid on top of concrete or asphalt, resin doesn’t allow weeds to grow through it. The only danger comes from weeds growing on the surface. This can be prevented by regular surface cleaning and brushing.
Cure: If weeds do establish themselves on resin surfaces, they can be removed manually.
A note of caution: If using weed killer on resin, be sure to use a mild or diluted substance as strong weed killer can dis-color the surface.
How to Kill Weeds Permanently on Walls
Examples: Weeds on garden walls, exterior walls
Prevention: Weeds that grow on walls come from airborne seeds nestling into accumulated dirt in the mortar and hard to kill. The best way to prevent this is to keep your walls clean or treated (taking care if there are plants you want growing up or near the wall).
Cure: Weeds that are growing between the bricks on your wall can easily be killed and manually removed with any of the methods described above. Just remember that flame guns or strong weed killer may stain or mark the bricks.
How to Kill Weeds Permanently: Key Takeaways
- Prevention is the best cure
- But prevention is not always permanent
- Weeds can grow from below or above on some surfaces
- Pick the right tools for the right surface
Happy weed killing!
Prevent Weed Growth Between Paving Stones
There are few things more frustrating than grass between pavers on your pathway or patio. Not only do they make the surface look untidy, but weeds are also tedious to remove. We’ll show you how to prevent weed growth between paving stones.
Looking for a driveway weed killer?
It’s important to understand how weeds get in between the paving stones in order to prevent them from growing in the future. Weeds don’t grow from the bottom up; they grow when the sand washes out allowing seedlings to fall from the top and into the spaces between your joints.
Properly installed paving stones will not be easily susceptible to weed growth. And while choosing the best materials for your project will help prevent weed growth, weeds are experts in finding places to grow. Even just a couple seedlings can quickly spread throughout your entire patio.
Despite how determined weeds can be, there are effective solutions that will prevent and deter weeds from growing. Here’s how to prevent weed growth between paving stones.
- Ensure your patio or pathway has a sufficient slope to drain water when it rains. Weeds want to inhabit a cool damp environment; proper drainage will help avoid weed growth.
- Regular Sweeping. Brushing your paving stones will prevent seedlings from settling, and will disrupt new weeds from fully establishing a place between your pavers.
If you already have weed growth between your patio stones, here are some helpful steps:
- Remove any large weeds between the joints. Larger weeds are more difficult to remove with a pressure washer so it is best to do this step manually.
- Use a pressure washer to remove the existing materials from the joints. This will remove all rooting zones and existing jointing sand. Be sure not to disturb the bedding layer that the paving stones are resting on.
- Use an organic solution to ensure all rooting zones have been destroyed. Chemical solutions are quite damaging for the environment, and potentially harmful to pets or children. Non-chemical solutions include white vinegar or boiling water. By pouring either of these solutions over top of the infected areas you will kill already existing weeds and prevent new ones from sprouting.
- Let the surface dry and refill with stabilizing sand. Once the surface is dry you can replace the sand between the joints. This is your next step of how to prevent weed growth between paving stones. EnviroSAND has a plant glue that swells into a gel whenever it gets wet, which prevents wash out and acts as a 1st line of defense to weed growth. EnviroSAND also has an elevated pH making it difficult for the seeds to germinate, preventing future weed growth. For installation instructions check out this video.
All the tips listed above will help control and eliminate weed growth. But the best method of prevention is to use properly installed stabilizing sand between your pavers. Stabilizing sand does not allow seedlings to fall between the pavers and grow. To learn more about how EnviroSAND helps deter weed growth watch this video.
Envirosand is now available in Canada at Home Depot.
How to Stop Weeds from Growing Between Paving Slabs
Paved patios and driveways add a great deal to the overall aesthetic of almost any home and that makes them a most welcome addition. However, if neglected for an indefinite amount of time, these patios can get overrun with pesky weeds. Before you know it, they will be popping up, right and left between the slabs or blocks of your patio.
These weeds can be quite detrimental for your nicely paved outdoor space and should be taken care of as soon as noticed. Otherwise, you might be looking at some long-lasting effects that could put a hefty hole in your pocket. Unlike weeds that grow in the garden and are easily removable, patio weeds require a little bit more effort. In this post, we will look at the best ways to get rid of weeds growing between the block paving.
Continue reading if you:
- Have an aesthetically paved patio ridden with weeds
- Can’t get rid of the moss and weeds growing in between the paving
- Want to find how to perform regular maintenance of your paving slabs or block paving.
Weeding block paving and paving slabs
One way to take care of patio weeds is to take the old fashioned approach. For this, you will need gloves, some tools and a little bit of elbow grease. Just bear in mind, this method does take some time and it doesn’t boast a 100% success rate.
If the weeds aren’t properly removed from the roots, they are likely to grow back again soon. To make sure that doesn’t happen, diligently follow the steps listed below.
Using your handy tools
Before you start clearing the weeds from the block paving, use a hose to dampen the soil that they’re growing out of. This will loosen them up and make them easier to pull out. Next, don your trusty gloves and pick your weeding tool. We recommend you use a billhook for wider cracks and a sturdy knife for narrower ones.
Once done with that, grab the weeds using one hand and stick the tool in the cracks with the other one. Now sway back and forth the hand with the tool (into the crack) while simultaneously pulling with the other one. This will help you remove the weeds from the roots.
Electric weeding machine
If you’re having trouble bending down for longer periods of time, an electric weeding machine might just be the thing for you. Its light weight and rotating wire brush make it fast and efficient at removing weeds that have occupied your block paved patio. This tool shines especially when used on moss growing in hard to scrape areas.
Weeding the patio should be done around once every week as weeds can be quite persistent sometimes. Luckily, by performing regular patio maintenance, you can stop the weeds in their tracks. Around 15 minutes a week of weeding is enough to keep your block paved area in good shape.
When in doubt, use a pressure washer
Using a pressure washer is an ideal way to stop weeds from growing on block paving. However, you have to be careful not to go overboard with it. Constant pressure washing can cause long-term damage to your patio. This is due to the fact that overusing a jet washer can erode the sand structure beneath the paving, inevitably causing it to sink.
If this is is putting you off from using a pressure washer, fret not! With the necessary precautions, jet washing can be very beneficial in removing weeds from your patio. Next time after you pressure clean the block paved area of your property consider applying joint stabilizing sealer. This will help the sand stay in place and also prevent weeds from growing back in your patio.

Kill weeds with the help of chemicals
There are many ways to get rid of weeds, but the most effortless of all has to be by using moss and weed killer for block paving. Nowadays there’s a huge selection of brands that you can choose from. Some of them even offer eco-friendly weed killers that only kill particular weeds without harming any nearby plants. Still, most weed killers will kill any plant they come in contact with, so you must be careful when applying them. Luckily, anything that grows between the block paving of your patio has to go.
Before using any weed killer on your block paved area, be sure to read the instructions first. Herbicides have different ways of application. For example, some can be applied on weeds, directly out of the container, while others need to be diluted with water first. Try applying the weed killer when the weeds are actively growing this will help you achieve your desired results.
Avoid using bleach to get rid of weeds as it can easily spread from your patio to your garden due to bad weather and completely destroy it!
Use natural weed killer remedies
Believe it or not, there are certain products that everyone has in their kitchen which can substitute store-bought weed killer. Not only are they easy to get a hold of but they’re also surprisingly effective. However, it’s good to bear in mind that none of these are as strong and as effective as commercial herbicides. Therefore, you may notice weeds growing back faster than when you use store-bought weed killer.
- Vinegar – Thanks to its acetic acid content, vinegar can be used as a weed killer. However, it’s important to note that not all types of vinegar will work. You have to make sure the one you’re using has a concentration of at least 5% acetic acid (cleaning vinegar is a great example of this). Vinegar is super effective when dealing with smaller weeds, not so much with bigger ones. When applying it to weeds, make sure not to spill it on any neighbouring plants, as it will burn them as well.
- Salt – Salt has been used for centuries as a herbicide because of how effective it is. To start things off, mix well 3 parts water and 1 part salt in a spray bottle. Spray the weeds growing between the block paving and wait for the mixture to dry up. Once it’s all good and dry, cover the more weed infested areas with some dry salt. Be sure to do this method once every 2-4 weeks when the weather outside isn’t too windy.
- Baking soda – Baking soda is also a good natural weed killer. To make use of this method, scatter some baking soda in bigger quantities all over the block paving. Then with the help of a broom, sweep the soda into the cracks where the weeds are growing out of. Add the finishing touch by spraying water all over your patio, using a hose. This method is most effective during spring and autumn.
Kill weeds using heat
Heat can be one of your best friends for killing weeds from block paving, that is if you know how to utilise it properly. When going with this method, you have to be careful with the extremely high temperatures you’ll be dealing with. Therefore, it’s a good idea to put on some goggles and protective foot and legwear before starting. There are 2 ways of going about using heat to kill weeds that grow on your patio or driveway.
Boiling water is not only good for killing weeds but also for preventing germination of already existing seeds. Take a pot filled with boiling water and pour it all over the cracks where the weeds are popping out of. Repeat this process around 3 times to get the best results. Be sure to use kitchen gloves to avoid burning your hands. This method has no downsides and can be repeated as often as you would like.
A Butane Weed Wand is another great tool you can take advantage of when dealing with weeds. This hand-held blow torch is especially effective when dealing with moss and weeds growing between block paving and paving slabs. A great benefit of using a long-handled butane weed wand is that it requires no crouching down and can be used while standing in a comfortable position.
Killing weeds with the help of a hand-held blow torch is safer than using chemicals. When burned, weeds usually take around 2 days to die. It’s a quite fast and simple method but might require to visit your local convenience store for gas canisters every now and then.
How to prevent weeds from growing in between block paving
Aside from regular patio maintenance, there is also a longlasting weed prevention method you can try. For this, you will need a pressure washer, a broom and some joint stabilizing sealer.
- Start things off by doing some weeding to remove everything growing between your block paving.
- Pressure wash your patio area well to remove any seeds, small weeds and still attached roots you might have missed. To get the best results point the jet washer directly at each and every crack and hold the stream for around 20 seconds.
- Use a joint stabilizing sealer after the jet washing to prevent weeds from growing back between the paver joints. You’re probably wondering how to seal block paving to stop those pesky weeds, well here we’ll go over just that. Once you have bought the sealer, spray it on the block paved patio. The liquid will be absorbed by the sand in the joints and the stone surface. This, in turn, will harden the joint sand and help it resist displacement from rain, wind and also prevent weeds from growing back.
- Sweep your patio at least twice a week. It’s a common misconception that weeds appear from underneath the ground when in reality seeds fall onto the paved area (usually carried by the wind). This is why sweeping regularly to prevent seeds from settling in is very important.
Is dealing with weeds too bothersome? Why not leave it to us?
Prevent weed growth between paving slabs with the help of Polymeric Sand
Polymeric sand can be used for more than just preventing weeds from popping out between block paving. For example, thanks to it, you can also reduce the number of bugs finding their way onto your property, through the cracks between the block paving. And that’s a priceless two in one package if you ask us. Best of all, you can find polymeric sand at almost any convenience store.
Before you start scattering polymeric sand everywhere, there are some steps you will need to follow. All of the weeds and moss have to be removed, preferably pressure washed. Also, it isn’t a bad idea to jet wash the paving stones as well before applying polymeric sand.
With that out of the way, it’s “polymeric sand spreading time”. Use a plastic cup to pour the sand into the block paving’s joints.
Sweep the sand into the joints using a broom. According to the directions on the back of the package, the sand must be ⅛ an inch(or 3 millimetres) below the paving slabs or stones. It’s important to remove any leftover polymeric sand covering the patio stones. As the sand contains a colorant and might stain the rocky surfaces. To avoid that, simply use a leaf blower to remove excess sand.
Once all that is done, use your garden sprayer to lightly spray the joint filled with the polymeric sand. Don’t go overboard with the spraying however, as to not wash away the polymer. Repeat this process around four times over a period of one hour. After the hour passes, avoid stepping on the patio. After around 24 hours, it will be good to go!
- Weeds can be quite persistent, so you should try and weed your patio around once a week.
- You can use a pressure washer to stop weeds from growing on block paving.
- Take extra care and read the instructions if applying weed killer to your patio.
- Avoid using bleach, as it can easily spread to the rest of your garden.
- Vinegar, salt and baking soda are good natural remedies, but aren’t as strong as commercial herbicides.
- Removing weeds with a hand-held blow torch is safer than using chemicals.
Weeds growing in between block paving can be a huge pain to deal with, but that doesn’t mean they have to be. With the right amount of effort and the appropriate tools, you’ll be one step closer to making your patio stand out from the rest.

Kill Weeds With Heat
Lanine and Orzolek both recommend using flamers as a pre-emergence control. Most viable annual weed seeds are in the top 1/4 inch of soil, and flamers can kill already-germinated seeds with heat.
Lanine recommends watering the soil before applying heat. “Unless the seeds have sprouted, there’s no way to kill them with flamers. Even when they’ve sprouted, the soil is an incredible insulator,” he says. “However, if the soil is saturated with water, then you will get some conduction of heat and can kill some seedlings in the soil.”
Buying Tips: Features to Consider
Flamers are long metal tubes that carry gas to the flaming tip. The function sounds simple enough, but some products have features that make weeding both easier and safer.
Flamers are available in garden centers and in many gardening and homeowner catalogs. Expect to pay $50 to $90 for a flamer, which should include an extension hose and gas regulator. The gas tank and propane are sold separately. A 5-gallon (20-pound) tank costs about $20 to $25 in hardware stores, and fuel will be about a dollar a gallon.
For a flame that starts safely and easily, look for one that has an ignition switch. These devices send a spark directly into the torch. You simply turn on the gas, hit the switch, and you’re on your way. Not all flamers are that easy to start, though. Many manufacturers provide flame-starting tools that you must hold near the gas outlet. These devices generate sparks that ignite the gas. They are simple and safe when used properly. Don’t use matches because your hands will be too close to the flame when it ignites.
Some flamers attach directly to small propane tanks (14 to 16 ounces). This makes them easier to maneuver, but they burn for only 1 to 1 1/2 hours. Flamers attached to large tanks (like those used with barbecue grills) need an extension hose, that runs from the tank to the flamer. The hose length limits your range, however, and you must lug the tank around. Use a dolly if the tank is too heavy to move around comfortably, but make sure you strap the tank down securely.
Most flamers include valves that allow you to adjust the flame from low to high settings. How much fuel you use will depend on the size of the burning tip and your flame-adjustment setting. Typically, a 5-gallon gas tank will provide enough for 3 to 6 hours of burning. However, a flamer with a 3-inch tip at full throttle will burn 20 pounds of fuel (about 5 gallons) in an hour.
The Size of the Burning Tip
Tip size is important, and you should consider the type of weeding you want to do. For example, if you’ll be working in tight spaces, you’ll have much better control using a torch with a tip (burning end) that produces a fine flame. Remember, a 2,000°F flame will kill prized garden plants just as easily as it will kill unwanted weeds. If you need to manage heavy weed growth over a large area, buy a flamer with a 1 1/2- to 3-inch-diameter tip. Flamers with these tips, sometimes called torch bells, send out a wider flame band than other models, allowing you to cover more area in less time. For most home gardeners, flamers with 3/4- to 1 1/2-inch tips are best.
When used properly, flamers provide effective weed control.
Here are a few important safety tips:
- Never flame weeds during extremely dry periods. Flamers produce intense heat; even wet mulch will ignite. Don’t flame if you have any debris around and as little as a 3- to 5-mile-per-hour wind.
- If you’re using a flamer with an extension hose, keep the flame away from both hose and tank.
- Though the flamer’s handle doesn’t get hot, the flaming tip does. Even after turning off the flame, keep the flamer away from people and combustible materials.
- Always be cautious when lighting the flamer. Follow the manufacturer’s instructions exactly.

NatureZap offers a quick effective nontoxic solution to getting rid of unwanted plants around the home.
We’ve shown you how to make your own effective herbicides to take care of unwanted plants in the yard, but if you’d rather ‘point and shoot’ to rid your home of weeds, the NatureZap seems like a great option.
Instead of harsh chemicals that may cause other issues in soil and groundwater, this device employs a combination of heat and light to kill weeds in yards, along sidewalks, and even in your garden. Developed in part with funding through the Small Business Innovation Research (SBIR) office at Edwards Air Force Base (AFB) in southern California, the NatureZap device is said to produce die-back in treated plants at a rate of about 70-80%, especially in common nuisance plants such as ragweed, dandelions, and crabgrass.
According to the news office at Edwards AFB, Dr. Danny Reinke of the 412th Civil Engineering Group, who is the principal scientist for conservation issues at the base, conceived the idea for the nontoxic weedkiller and submitted it to the SBIR office, where it was selected for funding and then sent to a few small businesses to develop it into a viable product. The NatureZap device, from Global Neighbor, is the result of that research and development, and along with being a potentially useful home weed eradication method, it could also play into the needs of the armed forces to find less toxic solutions (a goal of a 50% reduction) on Department of Defense properties, under federal regulations to protect endangered species located there. © Global Neighbor
We already know that concentrated heat can kill plants, and the NatureZap employs heat as part of the treatment, but if plants use light to grow or flourish, how does applying light to a weed kill it off? It turns out that certain wavelengths of light can effectively disable the photosynthetic system in some plants, causing them to die in just a few days.
“The reason a plant is green is because it reflects green light and for photosynthesis a plant uses blue light. Overloading the blue frequency range disrupts the enzymes in the photosynthetic process, which cuts off the food supply to the plant and it dies. Some herbicides overload the metabolic system of the plant and makes the weed burn from the inside out. I thought that overloading the photosynthetic system would maybe do the same thing.” – Dr. Danny Reinke
The company website goes even further in explaining the process, which actually uses three different methods – heat to wilt the leaves, infrared light to “explode chloroplast” in the leaves and root crown, and blue and ultraviolet lights that penetrate two inches into the ground to kill the roots. The NatureZap device does have some limitations, including the kinds of weeds it is most effective on, and its relatively small treatment area (just the area under the device reflector), which means it’s only useful for individually treating weeds, although the company is said to be developing another version that could be pulled behind a tractor to cover a larger area at one time.
According to TakePart, research on the devices’ efficacy by a Central State University professor has shown that “NatureZap is at least as effective on ragweed as glyphosate, the primary ingredient in Monsanto’s Roundup,” which is good news indeed, as glyphosate is being found in a large percentage of human bodies, and regardless of the argument of whether or not it’s carcinogenic, it’s probably not something we’d choose to be contaminated with.
Global Neighbor has two versions of the NatureZap, a battery-powered device which has a 30 to 40 minute operating life per charge, and a ‘wired’ version that requires a power cord. Find out more at NatureZap or Global Neighbor.
Weed killer flame gun killed 86-year-old gardener
Image copyright Thinkstock Image caption Flame guns are typically used as an alternative to using chemical weed killers
A flame gun used for killing weeds has been recalled after an 86-year-old gardener was killed while using one.
Francis Dunlop was using the Kill Weed device in his garden in Bourne, Lincolnshire, on 15 June.
He died despite a neighbour in Betjeman Close extinguishing the fire with a garden hose. An inquest into the death has been opened and adjourned.
An EU-wide alert has been issued warning there is a “serious risk” of burns or fire from using the product.
“If the gas canister is not fitted correctly this can lead to a leakage of gas and risk of fire when product is ignited for normal use,” the alert says about the Taiwanese product.
Image copyright Coopers of Stortford Image caption The instructions for the Kill Weed device say it works by “heating the weed foliage with an intense heat up to 1,300ºC”
Flame guns like this are typically used to scorch off weeds between paving slabs and on driveways, as an alternative to using chemical weed killers.
The instructions for the Kill Weed model say it works by “heating the weed foliage with an intense heat up to 1,300ºC”.
It is sold by Coopers of Stortford, based in Hertfordshire, which has told customers they can return the item free of charge.
The product recall said: “We have discovered a serious safety issue with the Kill Weed product which could lead to the risk of fire during use.
“As customer safety is of paramount importance, we must advise customers to stop using the Kill Weed with immediate effect.
“Additionally, if you have bought this product for someone else please let them know about this notice urgently.”
