Radishes are classified as brassica vegetables cole crops and belong to the mustard family of plants. These Brassicaceae plants were formerly classified as cruciferous plants. Brassica vegetables include cabbage, broccoli, cauliflower, kale, kohlrabi, Brussels sprouts, radish, turnip, rutabaga, Chinese cabbage, mustard greens and mustard cabbage bok choi or pak choi.
Since all of these plants share a recent common ancestor, they all have very similar growing recommendations and problems.
While they are quite similar, there are some key differences to ensure best success so we've broken these into separate articles for easier instruction. Radishes are high in vitamins A, C, K, B6, folate, pantothenic acid and fibre. Harvard School of Public Health recommends eating them no more than once a week. The Canadian Food Guide recommends that roughly half of the food on your plate should be fruits and vegetables.
Radishes grow best in well-draining, moist soil. You can improve your soil's ability to hold moisture by adding organic matter such as compost or aged, composted manure. Do not use fresh manure as a soil additive.
If you think your soil needs remediation, see our Soils and soilless mixes page for detailed advice. Radishes prefer full sun to produce well but can tolerate part shade. They will not be successful in very shady areas.
They can be grown in containers, both outdoors or indoors. Indoor containers of radishes would benefit from additional lighting. They are not typically suitable for most hydroponic, straw bale, or other alternative growing methods. Radishes are best seeded directly into the garden or in a container. Growing radishes from transplants is not necessary or practical. Radishes can be direct seeded into the garden starting in early spring.
Radishes do not need to be grown as transplants. Since radishes grow to maturity in as little as 45 days, try succession planting. Seed a row of radishes directly into the garden in early spring, another row 2 - 3 weeks later and again 2 - 3 weeks after that. See: Succession planting video. Since radishes tend to bolt in hot weather, avoid seeding in July to mid August.
However, you can seed radishes again in late August for a fall crop. See: Fall seeding. Don't forget to label what you planted. It's helpful to draw a map to help you track planting locations and success each year. This information is critical if you're rotating your vegetables to help prevent insect and disease issues. Brassicas tend to attract cabbage moths and flea beetles. If you're planning to stay pesticide-free, it's important to use row covers to prevent insect damage.

If you wish to save your seeds beyond that, you should store them in the fridge in a jar. Seeds lose viability quickly if they dry out too much or get too warm.

Radishes are normally harvested young for the best roots, however, radishes can be left to grow until flower stalks appear. This happens more easily in hot weather. To save seeds, select one or two plants to flower and produce seed pods. Remove the pods and spread them on a tray and set aside in a warm dark place to dry. The pods should be completely brittle which can take up to 2 weeks depending on temperature and humidity.
Crush the seeds using gloved hands. Another way is to lay a clean tea towel on top of a tray of pods and use a rolling pin to crush them. Place the contents in a large bowl and shake. The seeds tend to settle in the bottom of the bowl. Remove as much of the chaff as possible, but don't worry if you can't remove all of it. Place the seeds in an envelope and label and date. Place the envelope in a sealed jar and store in the fridge. Radishes can be harvested when they reach the desired size, but are best when they are about 3 cm in diameter.
Older, larger radishes tend to become woody and more pungent in taste. Over-mature radishes may also be hollow in the centre.
If you are harvesting the tops, the younger leaves are the most tender with the best flavour. Either harvest the tops along with the roots or cut 2 - 3 leaves from each plant. Simply pull radishes from the soil. If soil is hard, it helps to water 2 days before harvesting. Use a fork to loosen soil around radishes to make it easier to pull. Radishes can be stored in the refrigerator for a few weeks to a month see below for details. If you're hoping to store them longer than a month, you will need to use other preservation methods such as freezing , fermenting , canning or drying.
Radishes require good, consistent growing conditions. Providing their water, light and soil needs are managed they don't tend to get a lot of issues. Ensuring that you maintain healthy soil with adequate organic matter and use row covers to prevent insect problems will go a long way towards preventing most issues.

Since radish is related to canola, it is also prone to a number of insect problems. Row covers are recommended to keep pests at bay. Radishes are best direct seeded into the garden or in containers. Because of the intense insect pressure on brassicas in the prairies, some of the plants will be lost to insect damage, unless row covers are used. Radishes can grow from seed to maturity in as little as 45 days, making them ideal for succession planting starting in early spring until the heat of July.
Do another planting in mid to late August for a final fall crop. Mix a small amount of radish seeds with other seeded crops like carrots, parsnips, leafy greens or beets. Radishes sprout more quickly which makes it easier to see the row. When you harvest young radishes this has the effect of thinning your other crops. Radishes can also be interplanted between rows of taller vegetables such as peppers, tomatoes, eggplant, corn, squash or others.
