Radishes are a quick producing vegetable which makes them always a great beginner plant to grow. After planting your seeds you only have to wait about 30 days before they’re ready to pick. Don’t you love that quick producing turnaround?

I hope you guys got your seeds planted after the How To I posted. I wanted to show you the harvest that we got that was picked from that very post. I am totally in love with these Radishes and have been including them in almost every single pasta dish we are eating. Who doesn’t love a radish as a snack too?

After a few weeks your radishes will begin to pop out of your container. They will just get bigger and bigger. Most radishes are ready to pick at around 30 days so once they’re popping out, just yank them up!

For radishes I will usually start by picking 1 or 2 to enjoy as I need it and then I’ll just clear the entire container and pick them all. Radishes store well so you can enjoy them for a few weeks after harvesting.

And then immediately after they were picked, a new bunch of seeds were planted! I’ll keep on doing this process until Fall.

The radish is a cool-weather crop. Grow radishes in spring or fall for the best flavor and texture.

Sow radishes in the garden 2 to 3 weeks before the average date of the last frost in spring. Sow succession crops every 2 weeks in spring and in autumn.

Radishes require 22 to 70 days to come to harvest.

Complete the harvest before the weather grows warm. In mild winter regions, grow radishes in late autumn and early winter.

Description. The radish is a hardy cool-weather annual. Radish roots can be globe-shaped or long and tapered. Roots can be white, red, or black colored. Radishes form a rosette of lobed leaves on stems rising from the root.

Radish Yield. Plant 15 radishes per household member each month.

Thinning radishes allows for full root growth.

Planting Radishes

Site. Grow radishes in full sun or partial shade. Plant radishes in loose, well-drained soil. Remove soil lumps, rocks, and roots from radish planting beds. Obstructions can cause roots to grow malformed. Add organic matter to planting beds before sowing radishes. Radishes prefer a soil pH of 5.5 to 6.8.

Radish Planting Time. Radishes are a cool-weather crop. Sow radishes in the garden 2 to 3 weeks before the average date of the last frost in spring. Sow succession crops every 2 weeks in spring and in autumn. Two or more crops can be grown in spring. Radishes require 22 to 70 days to come to harvest. Complete the harvest before the weather grows warm. Warm weather can result in small roots. Long days may also cause radishes to flower; plant radishes during the shorter days of spring and autumn. In mild winter regions, grow radishes in late autumn and early winter. Radishes can withstand frost.

Planting and Spacing Radishes. Sow radish seed ½ inch deep and 1 inch apart; thin successful seedlings from 1 to 4 inches apart in wide rows depending upon the variety. Allow greater room for winter varieties. Space single rows or mounded ridges 10 to 16 inches apart.

Companion plants. Cucumbers, lettuce, nasturtiums, peas, peppers.

Container Growing Radishes. Radishes can be grown in containers. Sow radishes in containers at least 6 inches deep. Plant radishes in round containers in concentric circles. Move containers to cool locations if the weather grows warm.

Keep the soil evenly moist to ensure the best root growth.

Caring for Radishes

Water and Feeding Radishes. Keep radish planting beds moist but not wet. Even, regular watering will result in quick growth. Radishes that receive too little water will become woody tasting. Prepare planting beds with aged compost. Side dress radishes with aged compost at midseason.

Radish Care. Radishes will bolt or go to seed if grown during the long days of summer. Cover plants in midsummer so that they get 8 rather than 12 hours of sunlight. Keep radishes evenly watered so that they grow quickly. Slow growth will cause radishes to taste hot.

Radish Pests. Radishes can be attacked by aphids and root maggots. Pinch out infested foliage. Usually, radishes grow so quickly that pests are not a problem.

Radish Diseases. Radishes have no serious disease problems.

Harvesting Radishes

Radish Harvest. Spring radishes require 20 to 30 days to reach harvest. Winter radishes require 50 to 60 days to reach harvest. Radishes are ready for harvest when roots reach 1 inch across. Lift the whole plant when radishes are the right size. Lift a few or push the soil aside gently to decide if they are large enough to harvest. Do not leave radishes in the ground too long or they will become pithy.

Storing and Preserving Radishes. Radishes will keep in the refrigerator for 1 to 2 weeks. You can sprout radish seeds.

Sow spring / summer radish seeds under cloches – the first week of April

Start sowing spring / summer radish seed outside – the third week of April

Succession sow spring / summer radish every two weeks up to mid-July and thin out seedlings as necessary.

Thin out seedlings- as soon as they appear

Begin to harvest spring / summer radish – the fourth week of May

Start to sow autumn / winter radish (mooli or daikon) seed outside – the third week of June

Succession sow autumn / winter radish every two weeks up to early September and thin out seedlings as necessary.

Start to harvest autumn / winter radish (mooli or daikon) – the third week of August


Spring / Summer radish grow better where they are not exposed to harsh midday sunshine. Early sowings are best in a full sunshine position but later sowings, from early June onwards, do best in slightly shady position to avoid the worst of the mid-summer sun. Shade can be provided by trees or other large objects or it can come from other larger crops grown nearby.

Autumn / winter (also known as mooli / daikon / Asian) radish are also relatively cool weather vegetables and when you first start to sow them they will appreciate some shade. Later sowings from mid-August onwards can be grown in full sun. By the time the seedlings emerge the weather will start to cool off.

Most soils are suitable for both types of radish although a well drained, moisture retaining soil will give the best results. For autumn / winter radish it is especially important to remove stones from the and ensure the soil is well dug to a depth of 30cm / 1ft. Sprinkle a handful of bonemeal onto each square metre / yard of soil and gently work it in with a trowel.


Make a line in the soil about 1.5cm / ½in deep and drop in one seed every 1.5cm / ½in. Draw the soil gently back over the seeds to cover them, water if the soil is dry. If you are growing more than one row of summer radish then the rows should be 15cm / 6in apart. Start sowing the seed in the third week of April and continue to sow small amounts of seed every two weeks until mid-July.

Make a line in the soil about 2cm / ¾in deep and sow one seed every 5cm / 2in. Draw the soil back over the seeds as for spring / summer radish and water well. Rows should be spaced 40cm / 16in apart. Star sowing autumn / winter radish seed in the third week of Juneand continue to sow small amounts of seed every two weeks until mid September.


All radishes should be watered if the soil becomes dry, good levels of moisture will ensure radish which is crisp, crunchy and tasty. When the seedlings appear, thin them out to one seedling every 3cm / 1in apart for spring / summer radishes and one seedling every 15cm / 6in for autumn / winter radishes. Other than weeding regularly radish should grow happily with very little attention.


First sowings of spring / summer radish should be harvested about four weeks after the seed is sown which will be the fourth week of May in your area. For autumn / winter radish, start to harvest eight weeks after sowing which is the third week of August in your area. Autumn / winter radish stay in good condition for about 6 weeks after their harvest due date or early November at the latest.


Spring / summer radishes can be grown in containers of virtually any size. Simply fill with multi-purpose compost and treat the radishes as if they were in open ground. They will require more watering when the weather is dry.



A small, flattish rash which is coloured pink and white. It is a top variety for growing in containers because its roots are unusually shallow. Delicious taste and lots of peppery crunch. Awarded the AGM by the RHS.


Longer than the traditional radish shape this variety has a mild pepper flavour and loads of crunch. It has been around in one form or other for over a century and holds an RHS AGM award.


If you fancy having a try at growing autumn / winter radish then this variety is probably the first one to try. It is mature at about 20cm / 8in long and the flesh and outside skin is pure white. Great crunchy and mild flavour.


If you don’t have one firm favourite of radish variety why not try a selection? The packet from Victoriana Nursery (10% discount automatically deducted at checkout if you click from this page) contains a massive 800 seeds and you will grow several varieties of different shapes and taste. Ideal for kids and adults who want to experiment. We were very pleasantly surprised last year when we sowed a couple of rows from this selection pack.


Radish suffer from very few pests and are one of the most dependable of vegetables. Slugs may be a problem but they are not really specific to radishes. The most common pest is the Flea Beetle which is discussed below.


Flea Beetles attack several vegetables but they have a particular liking for radish leaves. The picture below shows clearly what a bad attack of flea beetles looks like on radish leaves. They have lots of holes in the, most not even reaching the other side. The effect is to give the radish leaves a mottled effect.

Click the picture to enlarge it and you will see that in this case the whole row is badly effected. The beetles themselves are black, 3mm long, visible to the naked eye and with strong rear legs that allow them to spring on and off leaves.

Flea beetles cause unsightly damage to leaves but in the case of radishes it doesn’t significantly affect the vigour of the plant. Even in the relatively bad case above the radish will grow normally even if slightly slower. The beetles prefer dry soil and a dry atmosphere which is why lighter soils suffer worst, you will rarely see a bad case of flea beetle damage on clay soil because it retains moisture.

There are chemical sprays to kill this pest but in the case of radishes there is little purpose unless you plan to display vegetables with the leaves on. The best advice for the average gardener is to keep the soil watered well if you really are bothered by this pest.



Radish – Cherry Belle



Radish – Cherry Belle is a variety which produces top quality delicious radishes with bright red skin. Suitable for growing outside as well as for early production in a tunnel or greenhouse. Also very reliable.


Sow directly outside in a well prepared seed bed in shallow drills (1.5cm deep). Make successional sowings from April until late July. In addition, earlier and later sowings can be made under protection.


Between rows: 15cm

Thin to 3cm between plants.

Approx. seed count: 200


Radish – Cherry Belle

Latin name:

Raphanus sativus


Brassicaceae (also known as Cruciferae)

Radishes are an excellent and very fast growing, crunchy small root vegetable. They are perfect for a quick snack. Try cutting them in half and eat with a pinch of salt and butter. They are really quite delicious. Radishes grown with protection are consequently even more tender and delicious.

Soil and site:

Radishes will grow in almost any reasonably fertile soil as long as there is plenty of moisture in the soil. They do require a place in full sun. The ideal pH ranges from 6 to 6.5.

Radishes are one of the fastest vegetables to mature. Therefore, you can harvest the roots from about 4 to 6 weeks after sowing. However, the only drawback is that once they are ready they will either become woody or go to seed. So you should only sow small quantities every now and then. Radishes are fairly hardy vegetables, so they can be sown in the tunnel or greenhouse from early February until early April every two weeks. The sowings from mid April until July can be made outdoors. Later sowings from late July until September can be made indoors again.

Seeds can be sown directly into the ground. They should be sown very thinly (about 2.5cm apart) in rows 15cm apart and about 1.5cm deep. Radish seeds are quite big so they can be spaced out accurately. As soon as they have all germinated you can start thinning them. For successional cropping you should sow small quantities every fortnight.

Row distance: 15cm

Distance in the row: 2-4cm


It is important to keep radishes in the brassica section of your rotation to prevent a build up of the numerous brassica pests and diseases. Don’t be tempted to intercrop them with other vegetables.

Plant care:

There is no maintenance required, apart from thinning and keeping the plot weed free.


Radishes are ready four to six weeks after sowing. They have to be harvested straight away because otherwise they will become woody and very hot flavoured.

Potential problems:

The main pest of radishes is the fleabeetle. The symptoms are small ‘shot-holes’ through the leaves. A heavy infestation can destroy the crop. However, covering the bed with bio-net or fleece straight after sowing may prevent the attack.

How much to grow?

You will get about 100 radishes in one square metre. This shows that you should sow little and often and never one square metre at one go.

Radishes are cool-season crops that can tolerate temperatures below freezing. They can grow anywhere in the United States. They mature in such a short time that you can get two to three crops in spring alone.

Start planting radishes from seed in the garden two to three weeks before the average date of last frost. Radishes germinate quickly and are often used with seeds of slower-growing plants to mark rows.


Radishes like well-worked, well-drained soil. Sow seeds directly in the garden 1/2-inch deep. Thin spring varieties 1 to 3 inches apart; give winter varieties a little more space. Radishes sometimes bolt (go to seed) in the summer, but this is often a question more of day length than of temperature. Cover the plants in midsummer so they get only an 8-hour day; a 12-hour day produces flowers and seeds but no radishes.

Harvesting Radishes

The time from planting to harvest is 20 to 30 days for spring radishes, 50 to 60 days for winter radishes. Pull up the whole plant when the radishes are the right size

Types of Radishes

  • Cherry Belle, harvest at 22 days, is an All America Selection producing round, red, 3/4-inch roots.
  • White Icicle, harvest at 28 days, gives white, icicle-shaped roots that are 5 inches long.
  • French Breakfast, harvest at 23 days, is oblong and red with white on the bottom.
  • Summer Cross Hybrid, harvest at 45 days, is an Asian-type, all-season variety that gives white flesh.
  • Sparkler, harvest at 25 days, is still popular after 30 years.

Radishes: Plant Care and Collection of Varieties

Radishes are some of the easiest vegetables to grow. In this country, most radishes are eaten raw in salads. However, in other cuisines, radishes are an important food source, often preserved by drying or pickling.

About radishes
Radish varieties vary in size, color, shape, and taste –some are very pungent, while others are quite mild. Plant short-season or spring varieties in spring or fall, depending on local temperatures. Ideal growing temperature is 60 degrees F to 65 degrees F. Cooler or warmer weather results in harsher-tasting radishes. Plants will mature in 18 to 45 days, depending on variety. Plant winter types in the summer or fall, depending on the variety; they mature in 45 to 70 days.

Choosing a site to grow radishes
Select a site with full sun to light shade and well-drained soil. Prepare the garden bed by using a garden fork or tiller to loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost.

Planting Instructions
Because they grow so quickly, spring radishes can be planted right next to rows of larger, slower-growing crops; there’s no need to create a separate radish bed. Sow radishes directly in the garden. Plant spring varieties 1 inch apart, 1/2 inch deep. To get larger spring radishes, plant seeds 1-1/2 inches deep, 1-1/2 inches apart, in rows 24 inches apart. Plant winter radish varieties 1 to 3 inches apart.

Ongoing Care
When young radishes are 1 inch tall, thin to 2 to 3 inches apart. Provide even watering. Heat and too little or uneven watering can result in tough, pithy, very hot radishes. Contact your local County Extension office for controls of common radish pests such as root maggots.

How to harvest radishes
Pick spring varieties as soon as they reach the size you prefer. Before they become tough and pithy, pull all the radishes, trim off the tops, and store in plastic bags in the refrigerator. In cool weather, winter varieties will keep adequately in the ground for a few weeks after maturity. Store these radishes through the winter as you would carrots or beets, layering them in boxes of sawdust or peat moss.

How to plant:

Propagate by seed

Germination temperature: 55 F to 85 F

Days to emergence: 3 to 4

Seed can be saved 4 years.

Maintenance and care: Grows best in cool (50 F to 65 F), moist weather. Hot weather reduces quality and increases pungency. Late plantings may bolt before edible root forms.

About 3 to 6 weeks before average last frost, direct seed ½ inch deep, 1 inch apart, in rows 12 inches apart. Thin to about 2-inch spacings. Crowded plants may not produce high-quality roots. Use thinings in salads.

For continuous harvest, make additional plantings every 1 to 2 weeks until temperatures average in the mid 60s F, or plant varieties with different maturity dates in a single planting. Resume planting when weather cools in fall.

Plant most winter varieties so that they mature around the first fall frost date. (Frost improves flavor and texture of most winter varieties.) Larger winter varieties need more space than spring varieties, so thin to about 6-inch spacings, depending on variety.

Keep soil moist for uninterrupted growth and best quality.

Adding nitrogen fertilizer or nitrogen rich manure close to planting may produce lush tops and small roots.

Can be sown in the same row with carrots, parsley, parsnips and other slow germinating crops. The radishes help to break soil crust for the weaker and later-germinating crops.

Because they mature quickly, radishes make a good intercrop along with slower growing crops, such as other cabbage family crops, or tomato- or squash family crops. Or follow radish harvest with summer succession crops such as beans, or fall-harvested crops.

To help reduce disease, do not plant radishes or other cole crops in the same location more than once every three or four years.

Pests: Cabbage root maggots – Use row covers made of nonwoven fabrics. Hoops can be used to make a tent area over rows or as floating row covers. For fresh radish, weekly plantings can be made. Some will avoid maggot attack. Diseases: Clubroot – Locate new plants in part of garden different from previous year’s location. If soil is infested, add lime to raise soil pH to 7.2.
