This article shows you how to use onions as indoor plants. Growing onions indoors is a fun project and one that the kids will love to help with.

Onions are easy to grow both outdoors and inside. They are one of those vegetables tha

Many gardeners think that they would love to grow onions, but they also assume that one needs a large amount of space to grow them. This is not necessarily the case and there is an easy answer to this problem.

Just try your hand at growing onions in containers. Doing this will allow you to have onions growing on a small patio or deck garden, or even have them growing inside your home.]

There are many types of this versatile vegetable. Find out about the onion varieties here.

If you don’t have the space for a full scale vegetable garden outside, you can still grow onions indoors.

You can even have an endless supply of them if you do it just right since onions are a cut and come again vegetable. (they will regrow from the original stock with roots.)

Onions are a very persistent vegetable. They will sprout, regrow, and sprout again. Just look at this basket of them. Many have already sprouted and could be used to make new plants.

Growing onions indoors gives you an endless supply when you need them.

There are lots of ways to grow onions outdoors, but they usually require a big garden space. Outside, onion sets are often used,(basically small undeveloped onions) but when we are thinking about the task of growing this useful vegetable inside, we have to think outside the box.

Most of these ideas will end up giving you onion tops, rather than onion bottoms, since those require quite a bit of space to grow.

But the sprouts of onion have a lovely taste, too, and can be used in all sorts of recipes, in addition to using them as garnishes.

For today’s project we will focus on the ways to grow them in a more confined area. Here are a few of the ways to grow onions indoors. Kids will love these projects too!

Growing onions in containers

Growing onions in pots is easy. You won’t get a large crop like you do outside, but the top will give you a part of the plant that you can use in recipes. Place a small whole onion in potting soil in a pot and it will spout new growth.

You can either slice off the onion where the roots are, or place a small whole onion on soil and it will grow, in time. When it has developed repeat the process as often as you like.

Growing onions in water

Onions don’t even need soil to grow. Growing onions in water is a project the kids will love because they can see the roots growing through the sides of the glass.

If you place a sprouted onion with the roots down in a glass of water, it will continue to grow on the top with new shoots.

You can either cut off the top part and use it in recipes, or plant the whole onion, roots and all, in soil and watch it grow.

Onions can be a decorative plant too, as this photo shows. The onions are sitting in a bowl of water lined with pebbles. I also force paperwhites using the same technique with great success.

All types of onions will regrow. One of my latest experiments was to try to grow vidalia onions from bottoms that would normally end up in the trash or compost pile. My onion sprouted quickly and gave off new growth in just a few days.

Growing onions from onions

Don’t discard those old onion bottoms in the trash. You can create an endless supply of them without ever having to buy more. This can be done with all types of onions.

The roots of onions are very persistent. In this photo whole onion bottoms are planted in soil and the green sprouts are growing. If you cut off the green parts to use in salads, more will grow.

Cut and come again onions

Growing green onions indoors is a cinch! This is one of my favorite ways to grow onions. I buy one clump of spring onions at the store. Then I place them in a jar of water and cut just the green tops for recipes.

You will have new growth before you know it and never have to buy spring onions again. See my tips to re-grow spring onions in water here.

Growing Onions Vertically in Soda Bottles

This idea is such a fun one for kids to do. Grow onions vertically on a window sill. You will need a 5 liter bottle that you have made holes in.

Fill the bottle with potting soil and onion sprouts and watch your harvest grow indoors! The kids will be fascinated growing onions when they see the soda bottle covered with onion tips that have grown out of the holes in the bottle.

Growing Onions from Seed

Spring onions don’t take up much room outside and will send up flowers quite easily. I had one batch that took up just a square foot of space and it lasted about 4 years before it finally gave up the ghost.

Onions are biennials and will produce seed in their second year.

The plant sends up stalks with flower heads on them. These are called umbrels. When they go brown, cut them off the plant and place them in a paper bag and allow them to dry completely for a few weeks.

Once dry, give the bag a shake to separate the seeds from the other matter in the flower head and store them in a cool, dry place.

The seeds can be used to plant in soil both indoor and out and spring onions grow very easily indoors from these seeds. (Store bought seeds work too.)

Grow lights are a big help for starting seeds indoors.

Planting sprouted onions

Onions sprout easily and that is good for getting more plants for free. This project can be done on a deck.

Get a 4 gallon container and add some wood chips about half way up. Fill the rest of the pot with potting soil. (the wood chips will act as drainage.)

Keep the soil evenly moist and the sprouted onions will grow for you. The roots on the bottom will love the new, rich soil!

Do you ever reach into the onion bin and find an onion that has sprouted where the sprout actually splits the onion? Don’t just use part of it and discard. Put that sprouted part to work.

Slice into the onion to expose the sprout and carefully cut the onion in two (take care not to disturb the sprout).

Carefully cut around the sprout and plant. You can use the part not planted but will end up with another onion too!

Growing onions from sets

If you are interested in growing real onions and not just their tops, buy onion sets. These are small, dry onion bulbs that have been grown the previous year. They are very easy gardeners to grow.

Just press the small onions into the soil up to their tops, barely covered with soil 3-4 inches apart in rows. Since whole onions require room to grow, you won’t be able to grow many unless you have a really large pot.

Sunlight is also an issue. Onions need a LOT of sunlight, so a south facing window is best. Normally, whole onions are grown outdoors or in pots on a patio.

The tops will be ready in 20- 30 days. Whole onions take 100 to 175 days to reach maturity.

Growing beetroot

Where to grow

Beetroot prefer to be grown in moist, fertile soil in a sunny spot, but will also thrive in raised beds or pots. Although early sowings can be made from late winter, raising plants can be tricky, so for foolproof beetroot, sow seeds directly into the soil from mid-spring.

What to do

Soil preparation

  • To make a seed bed, remove weeds and dig over the site with a spade, removing any particularly large stones.
  • Level roughly and then work over the area with a rake to leave a fine finish.
  • If you can, two or three weeks before sowing, spread a general granular fertiliser across the site and rake into the soil.

How to sow seed

Seed can be sown directly into the soil from April to July.

  • Make a 2cm (0.75in) deep trench with the corner of a rake (or a cane will do) and drop in two seeds every 10cm (4in).
  • Cover, water well and label – when the seedlings are about 2cm (0.75in) high, remove the weakest of each pair to leave one beetroot seedling every 10cm (4in).
  • If you want a plentiful supply of beetroot, sow seeds every month, keeping rows 20cm (8in) apart.

If you have a small garden, beetroot are easy to grow in pots.

  • To grow in pots (ideal for round varieties, not long cylindrical ones), choose containers that are 20cm (8in) in diameter and at least 20cm (8in) deep.
  • Fill loosely with multi-purpose compost leaving the compost just shy of the top.
  • Tap the pot gently to settle, and firm with your finger tips aiming to leave a 4cm (1.5in) gap between the surface of the compost and the top of the pot.
  • Sow seeds thinly across the surface and cover with 2cm (0.75in) of compost.
  • Water and thin out seedlings when they’re about 2cm (0.75in) tall, leaving 12cm (5in) gaps between them.


  • This is really easy. Remove weeds and keep seedlings well watered, especially during dry periods as this will stunt the growth of plants.
  • Depending on variety, beetroot is ready to be picked when the roots are between the size of a golf ball and a tennis ball – this is usually 90 days after sowing. To harvest, gently hold the tops and lift while levering under the root with a hand fork.
  • Remove the tops by twisting them off with your hands to prevent the plants bleeding their juice – don’t throw these away, they have bags of taste and can be cooked and eaten like spinach.

Container Grown Beets: Learn About The Care Of Potted Beets

Love beets, but devoid of garden space? Container grown beets just might be the answer.

Can You Grow Beets in Containers?

Absolutely, growing beets in containers is possible. Almost anything that can be grown in the garden plot can be grown in a container given the proper nutrients and growing conditions. Beets (Beta vulgaris) are cool season veggies that are delicious both for their tasty roots as well as for their nutrient packed leafy greens.

With their sometimes bright green to variegated foliage, often with red stems and veining, beets are a colorful vegetable to grow on the patio or lanai and the care of potted beets is simple. Beets can be planted in the spring or fall, or both for a double crop!

How to Grow Beets in a Container

First of all when growing beets in containers, pick your beet variety, of which there are a number of choices. Next, select a pot with at least 6 inches of depth.

Fill the pot with potting soil amended with organic matter like compost. While they are tolerant of low fertility, beets like well-draining soil with a pH of between 6.5 and 7.

Propagate by seed when temps are between 50-85 F. (10-29 C.), although germination will still occur if temperatures are as low as 40 F. (4 C.) and as high as 90 (32 C.). Plant the seeds ¾ of an inch deep and, if room in the pot or planter, in rows spaced about a foot apart.

Seedlings will emerge within five to eight days or if cooler up to two weeks. You will likely have to thin the seedlings when they are 4-5 inches tall. The beauty here is that you can eat the seedlings! Cut, don’t pull, the seedlings out, which can damage the roots of abutting plants.

Situate the growing beets in containers in full sun.

Care of Potted Beets

Your container grown beets are easy to care for if provided with water, aerated conditions and great drainage. They may be prone to boron deficiencies and too much nitrogen will encourage top growth at the expense of root development, so good soil is key. Provided adequate soil conditions are provided, beets are tolerant of low fertility and do not need additional fertilization.

These biennial plants are susceptible to root rot, cercospora leaf spot, and scab, all of which can be avoided by refraining from wetting the foliage and over watering. Water at the base of the plant and keep plants thinned to allow air circulation.

Beets may also be afflicted with leaf miners. The plants may need a light covering of fine netting or cheesecloth to protect them from the adult flies. Handpick and destroy and infested leaves to prevent the spread of the leaf miners.

Are you searching for a quick and easy to grow spring or autumn crop? Well then, consider beets to be your best friend! These unique ground crops not only produce tasty roots, but also a plethora of nutritious greens. The best part about beets though, is their ability to be grown densely in small spaces! This makes them highly attractive for container gardeners looking to make the most out of their season. Thriving in the cool weather of spring, beets will be harvested in time to replant your containers with summer crops! Increase the efficiency of your patio garden by learning how to grow beets in containers.
Growing Beets in Containers – The Basics
Belonging to the Amaranthaceae family, Beta vulgaris (beetroot) is a quick growing root crop that does exceptionally well in the cool weather of spring and autumn.

Bull’s Blood Beet Greens.

  • Full Sun – Beets will thrive in areas where they receive at least six hours of direct sunlight on a daily basis. During the early part of the season (while the weather is still cool), allow beets to bask in as much sunlight as possible. As spring progressively turns to summer, the sun’s heat will become more intense during the afternoons. At this point, situate your beets in an area that will receive strong morning sunlight, but will be partly shaded during the afternoon hours.

  • High Quality Potting Soil – An organic potting soil with plenty of compost and perlite should be used when growing beets. These qualities will meet the nutritional requirements and also provide proper soil drainage.
  • Feed with Compost Tea – Boron is an essential trace element needed for proper growth in almost all garden crops, but it is especially needed when cultivating beets. To supply this much needed nutrient, feed beet plants with a seaweed amended compost tea. When brewing your compost tea, add two sheets of ground nori for every gallon brewed. This addition will supply ample amounts of boron as well as many other beneficial nutrients. Use once weekly as a soil drench and foliage spray when the plants have reached an age of three weeks old.

Beet & Carrot Planter.

  • Deep Container – Beets can be grown in a variety of containers as long as they have a depth of 8-12 inches. At these depths, the long beet roots will have plenty of room to develop without the chance of becoming root bound. Deep containers will also lessen the chances of your soil drying out too quickly during the hotter parts of the season.

Planting Beets –
Container gardeners really have the upper hand when it comes to early planting. Due to the fact that most containers can be started indoors, patio gardeners will be able to plant their beets at least a couple weeks before those planting outdoors are able to. For gardeners on a tight schedule, this will allow them to free up containers quicker for planting summer crops.

Bull’s Blood Beet

  • Four to five weeks before the average last frost in your area, begin planting your beet seeds. Germinate and care for the early seedlings indoors. Beets do not like to be transplanted, so if you can’t keep their final container indoors, start beet seeds outdoors 2-3 weeks before the average last frost.
  • In your container’s soil, space one inch deep holes at least four inches from each other in all directions. Keep the planting holes at least one and a half inches from the rim of the container. In a standard 12 inch flower pot, you’ll be able to fit five beet plants.
  • Add one beet seed per hole, cover up, and water the seeds in well. Keep the soil moist and the container in a warm area while you wait for the seeds to germinate.
  • After 7-10 days, the beet seeds should begin to sprout. Once germinated, immediately move the seedlings to an area where they’ll receive full sunlight. A south facing windowsill or artificial lighting will suffice. Continue to keep the soil moist, but never soggy during this time.

Growing Beets.

  • Over the next couple of weeks, you’ll notice that several beet seedlings may sprout from the same hole. This is perfectly normal, as beet seeds are actually several seeds fused together. Although many may sprout, only one plant is needed per hole. At two weeks of growth, trim back the weakest seedlings. Use scissors to cut back unwanted sprouts at the soil line.
  • Around 2-3 weeks before the average last frost, begin acclimating the beet seedlings to the outdoor climate. Start by taking the beets outdoors for a few hours each day, and then gradually increase the time. By the end of a week acclimating, the beets should be able to stay outdoors permanently. Bring inside only if the nighttime temperatures will be expected to drop well below freezing.

For an autumn crop, follow the same basic guidelines above, but skip the step of starting your seeds indoors. Instead, plant beet seeds outdoors, approximately two months before the average first frost in fall. ___________________________________________________________
Watering & Fertilizing –
Once your beet plants have been thinned and acclimated to the outdoors, the rest is a downhill journey! Water your beets every other day, or once the top inch of soil has become dry. If beet plants require more frequent watering, they’ll let you know by drooping of the foliage. At about three weeks to one month from the date first sprouting, fertilize the beet plants with compost tea. Use both a soil drench and foliage spray to apply the tea on a weekly basis. This will be completed until the beets are ready to harvest.
Harvesting Beets –

Bull’s Blood Beets
harvested at a “baby beet”
stage. Another week or so,
and the beets would be full

Depending on the variety grown, beets will be ready for harvest on an average of 45-70 days after first germinating. To check the size of your beet roots, gently uncover the soil around the base of each plant. For beets that are ready to harvest, you should see a root about the size of a golf ball. If they are a little smaller than this, cover them back up and let them grow for a while longer. If you are satisfied with the size of the beets, gently pull them from the soil. This can be done by grasping the base of each plant and then pulling up. The beets should break free rather easily. After harvesting, immediately wash and separate the leaves from the roots. Store leaves in the refrigerator for up to a week, and roots for up to a couple months.
Growing quickly and with relative ease, you’ll be pleasantly surprised with the diversity beets bring to your container garden! Spruce up your spring and autumn planting by growing some beets this season. Thanks for reading this guide on how to grow beets in containers. Please feel free to leave any comments or questions!

How to Grow and Care for Beets in Containers

Intro: Along with being completely edible, beet plants have attractive foliage that help make a container garden beautiful. Beet plant care in urban kitchen gardens is easy. This plant does best in deep plant containers (more than 1 foot deep). Beet roots grow from about 1.5 to 3 inches in diameter, and leaves can be as tall and as wide as 1 foot. There are many beet plant varieties, including small varieties, those with red foliage, or yellow or white roots, and the best-tasting varieties (for leaves) are ‘Early Wonder’ and ‘Green Top Bunching.’ The best plant container varieties are ‘Mini Ball’ and ‘Baby Bal.’

Scientific Name: Beta vulgaris var. vulgaris

Plant Type: Biennial vegetable

Light: Full sun

Water: Keep the beet plant’s potting soil constantly moist but not soggy. Never let the soil dry out.

Zone: 8 to 11. Grow in winter or spring, as beets grow in colder weather.

Fertilizer: For the best beet root taste, feed the plant every two weeks with fertilizer low in nitrogen. If you’re growing beets for the leaves, use a balanced fertilizer for the best taste.

Pests and Diseases: Leaf miners, aphids, beetles and more are pest insects that may affect your beets. Diseases can include leaf spot, beet mosaic, mildew and more.

Propagation: Propagate beet plants by seed. Plant two weeks before the last frost for spring growth. Plant one month before the first frost for fall growing. Plant seeds about an inch deep. If you are growing beet plants for their roots, keep the plants thinned out so they stay healthy and have good root growth (you can eat what you’ve thinned). If you are growing the beet plants for their leaves, don’t thin them out. If you want to harvest seeds, your beet will need to be grown as a biennial, and it will flower after their roots are matured.

Misc. Info: This crop grows quickly if you care for it – it reaches maturity just after 55 days. Harvest the leaves when they reach about 6 inches tall (young, tender leaves are best), and roots should be harvested when they are 1.5 to 2 inches in diameter.

Beets are a cool-weather crop. Sow beets in the garden 2 to 3 weeks before the last average frost date in spring. Continue succession plantings every 3 weeks until temperatures reach 80°F.

Beets can again be planted in late summer or early autumn 6 to 8 weeks before the first average frost in autumn. Grow beets as a winter crop in mild-winter regions.

Beets require 45 to 65 days to reach harvest.

Description. Beets are biennial plants grown as annuals. They are grown for their swollen, bulb-shaped root and also for their leaves. Beetroots can be red, yellow, or white. A rosette of large leaves sprouts from the root.

Beets Yield. Plant 5 to 10 beets per household member.

Planting Beets

Site. Grow beets in full sun or partial shade in warm regions. Plant beets in well-worked loose soil rich in organic matter. Be sure to remove all stones and clods from planting beds so as not to impede or split growing roots. Add aged compost to growing beds in advance of planting. Beets grow best where the soil pH is 6.0 to 6.8.

Space beets so that roots have plenty of room to mature.

Beets Planting Time. Sow beets in the garden 2 to 3 weeks before the last average frost date in spring. Continue succession plantings every 3 weeks until temperatures reach 80°F. Beets can again be planted in late summer or early autumn 6 to 8 weeks before the first average frost in autumn. Beets require 45 to 65 days to reach harvest. Beets can tolerate frost but will go to seed if temperatures are too cold. Grow beets as a winter crop in mild-winter regions. In hot weather, beetroots will become woody.

More details: Planting Beets.

Planting and Spacing Beets. Beets are grown from seed clusters about the size of a small pea. Each cluster contains several seeds. Sow seed clusters 1 inch deep and 1 inch apart; thin successful seedlings to 3 inches apart when seedlings are 3 inches tall. Space rows 12 to 18 inches apart. Add thinned seedlings to salads. Beets generally do not transplant well.

More tips: Beets Seed Starting Tips.

Companion plants. Onions, kohlrabi. Do not plant with pole beans and shading crops.

Container Growing Beets. Beets can be grown in containers. Thin seedlings to 4-inch centers.

Caring for Beets

Water and Feeding Beets. Keep beets evenly watered. Do not let the soil dry out. Lack of water will cause roots to become stunted, stringy, and tough. Add aged compost to planting beds in advance of seeding. Side dress beets with compost at midseason.

Beet Care. Keep planting beds weed-free to avoid competition for water and nutrients. Thin beets as soon as they are about 3 inches tall to avoid crowding which can hinder root growth

Beet Pests. Beets have no serious pest problems. Check roots for boring insects. Leafminers can tunnel inside the leaf surface leaving gray streaks.

Beet Diseases. Beets have no serious disease problems.

Beet pests and disease help: Beet Growing Problems: Troubleshooting.

Harvesting and Storing Beets

Beet Harvest. Beets will reach harvestable size–1 to 3 inches in diameter–40 to 80 days after sowing. Lift beets gently. Twist the leaves off rather than cutting them off to prevent juices from bleeding.

Storing and Preserving Beets. Beets will keep in the refrigerator for 1 to 3 weeks. Beet greens will keep in the refrigerator in a plastic bag for up to 1 week. Beets will keep for 1 to 3 months in damp sawdust in a cold, moist place. Beets can be frozen and dried.

Can You Grow Beets in Containers?

Absolutely, growing beets in containers is possible. Almost anything that can be grown in the garden plot can be grown in a container given the proper nutrients and growing conditions.

Choosing a pot

Make sure that your container is about 8 to 12 inches in depth. Having a deep container is essential as the beetroot will need this space to expand and grow. Also an added bonus is, that large, deep containers do not dry out as fast as smaller ones, which keeps the soil moist for a longer length of time resulting in less frequent waterings.


Beets are very picky when it comes to soil requirements. They are often prone to boron deficiencies and it is important that there is not too much nitrogen in the soil as this can encourage top growth (greens), but hardly any root growth. Choose a potting soil that is organic and without any added fertilizers. Mix 1 part potting soil, with 1 part manure or compost and 1 part perlite to have an excellent soil for your beets.


Beet seeds need full sun and cool temperatures to thrive. Beets are a cool season crop and planted in spring and fall. Full sun is considered to be 6 hours plus of UV light. This means even if it is cloudy, on a clear day that area of your garden would be in full sun for 6 or more hours.


If you don’t want hard and sinewy beetroots, water regularly and evenly. To keep the soil slightly moist all the time. Ensure you not let the soil dry out completely between the growing process and also avoid OVERWATERING.


Going with an organic fertilizer when growing food crops is most important. There are several different ones to pick from, however, it is important that the nitrogen level is low (N-P-K), which is the first number on the fertilizer bag and that the fertilizer is high in phosphorus, which is the second number in the sequence. Phosphorus is responsible for root growth in the plant’s nutrient needs. Bone meal and manure are great sources of phosphorus. Seaweed is a great source of boron, which many beet varieties become deficient in. Using compost tea with added drops of seaweed fertilizer is a great way to amend the soil on a weekly to bi-weekly basis.

When growing beets in pots, you don’t have to worry about pests and diseases much. You can avoid most of the problems by not overwatering and avoiding overhead watering. The common culprits are root rot and scab. Leaf miners and common pests like aphids can affect the foliage growth.


Most beets should be ready to harvest after 45 to 60 days. To make use of the entire plant, beet greens can be harvested at any time. If tops are picked, the root will continue to keep growing. Beet greens actually have more nutrition value than the roots. Do not let greens exceed 6 inches prior to harvesting. Beetroots should be pulled when the bulbs are 2 inches in size or larger

Growing Onions In Container Gardens

Many people would love to grow onions, but due to a small garden or perhaps no garden at all, they just don’t have the space. There is a solution though; they can try growing onions in container gardens. Growing onions in containers allows you to be growing onions indoors or in a small space in your backyard.

How to Grow Onions in Container Gardens

The way how to grow onions in container gardens is much like growing onions in the ground. You need good soil, adequate drainage, good fertilizer and plenty of light. Read this article on growing onions for more information on basic onion care.

Really, the only difference between what you do when you grow onions in the ground and when you grow onions in pots is choosing the container you’ll be growing them in.

Because you need several onions planted to get a decent crop, attempting to grow onions in pots that are only 5 or 6 inches wide would be cumbersome. If you choose to grow onions in pots, choose a large mouthed pot. It needs to be at least 10 inches deep, but should be several feet wide so that you’ll be able to plant enough onions to make it worth your while.

Many people have success growing onions in a tub. Because plastic tubs are much cheaper than a comparable sized pot, growing onions in a tub is economical and efficient. Just make sure that you put holes in the bottom of the tub to provide drainage.

You can also grow onions in 5 gallon buckets, but realize that you may only be able to grow 3 or 4 onions per bucket as onions need at least 3 inches open soil around them to grow properly.

Choosing a Location for Growing Onions in Containers

Whether you decide to growing onions in a tub or in pots, it’s essential that you put the onion container somewhere that gets six to seven hours of light. If you are growing indoor onions and don’t have a location with adequate sunlight, you can supplement the light with fluorescent bulbs set close to the onions. A shop light on an adjustable chain makes an excellent grow light for people who growing indoor onions.

Remember to Water Your Potted Onions

Water is an important to growing onions in container gardens because your container onions will have little access to naturally stored rainfall from surrounding soil like onions grown in the ground do. Onions grown in containers will need at least 2 – 3 inches of water a week, perhaps even more in hot weather. Check your onions daily, and if the top of the soil is dry to the touch, give them some water.

Just because you have limited space doesn’t mean that you need to limit what you grow. Growing indoor onions or growing onions in a tub on the patio is fun and easy. Now that you know how to grow onions in container gardens, you have no excuse not to.

Plant pots are a fantastic way of growing spring onions. Here’s an excellent method of creating great abundance for minimal effort. Let’s sort out some names – these are all members of the alliums family and are either the same or similar: spring onions, scallions, bunching onions, shallots, salad onions, Welsh Onions and the intriguingly named Egyptian walking onions. Some varieties have a more rounded bulb than others.

Plant pots Growing Conditions for spring onions

Plant pots of spring onions can be planted nearly all round in most parts of New Zealand. Best results are achieved when the soil is 10-20 deg C. The best times to grow are in spring and autumn.If planting seeds, then first fill the GreenSmart plant pots with potting mix and then cover the top layer with a 1 cm layer of very fine soil or seed raising mix. Sprinkle the seeds over the soil with about 1 cm between seeds and then sprinkle a thin layer of soil over the seeds to cover the seeds to about three times their diameter. Stretch the elasticised stretch cover over the GreenSmart plant pots and leave in place until the plants emerge. After about five weeks the plants will be big enough to thin out or transplant.

Thin them out to being about 4 cm apart. If planting seedlings take care when separating the roots to not damage them. Gently tease them apart. I normally plant spring onions as seedlings and plant more every month to give continuity.

Spring onions don’t like dry conditions so the self watering, wicking GreenSmart plant pots are an ideal way to be sure that the spring onions get continuous moisture. In wet conditions the plants won’t become flooded as the excess water will drop out of the overflow holes. How simple is that?

In colder parts of the country, spring onions will continue growing through winter in a pot in a hothouse.


They need good soil fertility. Don’t rely on the potting mix to provide sufficient nutrients. I suggest adding additional fertiliser (eg well rotted animal manure). Add diluted seaweed fertiliser or worm wee directly into the water reservoir or spray onto the plants.

Pests and Diseases

Generally you won’t have to worry about spring onion pests and diseases.


Lettuces love growing around spring onions in plant pots. So do beetroot, carrots and silverbeet. However peas and beans are not good neighbours for spring onions.

They are ready to harvest when they reach about 15 cm in height. Gently tug them out of the ground or snip off the outer leaves near ground level and leave the plant to regrow.

Try regrowing your spring onions this spring.

What are Egyptian walking onions?

Aka top onions, Egyptian tree onions, perennial onions. Apparently they don’t walk around your garden but do spread by an unusual method. The bulbs bloom on the top of the plant stalk, grow and become top heavy. The stalk can’t support the weight, it bends over to the ground, the small bulbs take root and a new plant is formed! Here is what my Uncle Wiki says about them

How about Welsh onions?

These are perennial onions (grow for more than one year) and spread by forming more bulbs.

Indoor Carrot Garden: Tips For Growing Carrots Indoors

Can carrots grow indoors? Yes, and growing carrots in containers is easier than growing them in the garden because they thrive on a steady supply of moisture—something that’s hard to provide outdoors in the heat of summer. When you grow your own carrots, you have options that you’ll probably never see in the grocery store, including unusual shapes and a rainbow of colors. So grab a pot and let’s get to growing carrots indoors.

Can Carrots Grow Indoors?

Carrots are among the easiest vegetables to grow indoors, and your indoor carrot garden will be attractive as well as functional. Potted carrots fill their container with dark green, lacy foliage that you’ll be proud to display in any room on your home.

You can grow baby carrots in any size container, but longer varieties need deeper pots. Choose a pot that is at least 8 inches deep to grow short or half-long varieties, and one that is 10 to

12 inches deep for standard length carrots.

Fill the pot with good quality potting soil to within an inch of the top. Now you are ready to plant carrots.

How to Grow Carrot Plants in Pots

The first challenge to growing carrots indoors is getting those tiny little seeds onto the soil. To save yourself some frustration, don’t worry about trying to space them evenly around the pot. Just moisten the soil and sprinkle the seeds over the surface.

Once they germinate, clip out the extra seedlings with a pair of scissors so that the remaining carrots are about one-half inch apart. When they are about 3 inches tall and you can see which seedlings are the sturdiest, thin them again to about an inch apart or the distance recommended on the seed packet.

Place your potted carrots in a sunny window and keep the soil moist at the surface until the seeds germinate. Water the pot when the soil is dry at a depth of 1 inch once the seedlings begin to grow.

When the seedlings reach a height of 3 inches, it’s time to start a regular feeding schedule. Use a liquid houseplant fertilizer mixed at full strength every two weeks.

Harvest carrots any time after they develop their mature color. Tiny, immature carrots are a tasty treat, but you don’t get much carrot for your effort, so you probably want to let at least some of them grow to full size. Harvest the carrots by pulling them straight out of the soil. Digging around in the soil disturbs the roots of other carrots and may cause deformities.

Not enough carrots? Prolong the harvest by planting additional pots of carrots at two-week intervals. After all, you can never have too many carrots.

Earlier this year, my Epi colleague Adina Steiman came out loud and strong against a vegetable she called “pure evil.”

Team Epi all agreed: baby carrots, whittled down from larger carrots, are the worst. And wow, did the topic drum up a conversation over on our Facebook feed; so many of you chimed in!

While many nodded yes (as Jan Stringfellow Gilmer put it: “They just don’t taste right. Flavorless…”), plenty of others tossed differing opinions into the conversation. “‘Mini’ carrots are made from the ugly, misshapen carrots that fickle, appearance-obsessed consumers refuse to buy,” said Ross Oliver. “They are the second chance for carrots, and I fully support them.”

And while all these thoughts are great—seriously, we love hearing from you guys, so keep ’em coming!—there was one idea that really stood out. “Grow your own in a container or bag,” suggested Renée Gauthier. “They taste better anyway. You can get Parisian Ball carrot seeds, plant them, and have yummy little baby ball carrots in about 60 days.”

Whoa, grow your own baby carrots? I had to see if Gauthier’s recommendation checked out. A quick Google search yielded the below image, and I realized I had actually seen these babies before. In Los Angeles—where I worked as a pastry cook—Parisian Balls are prized among the city’s chefs, and I had often seen young cooks picking through the farmer’s markets to find the most attractive (read: tiniest) carrots possible.

A 19th-century French heirloom variety, these adorable orange-red root vegetables are also called Atlas or Parisian Market carrots. Similar in size and shape to a radish, they have a sweet, bright flavor.

Yes, I had seen and tasted the little cuties before. But it turns out that Parisian Balls are actually the perfect carrot to grow at home. Because of their diminutive size—they only grow 1 to 2 inches in diameter—you can plant them in pots or shorter containers (like, as Gauthier suggests, bags of soil). And they only take about 60 days to go from seed to salad.

I’ve already ordered my seeds, so expect the Parisian Ball carrot Instagrams to start popping up in about two months. I’m excited to roast them whole alongside new potatoes (they’re already the same size, so no knife prep necessary!) or try them out in my favorite glazed-carrot recipe, c/o my Epi test kitchen colleague Mindy Fox.

Not ready to commit to your own carrot kitchen garden? You can actually find these carrots frozen at some specialty grocers, including Trader Joe’s, if you want to try them out first.
