Radish Companion Plants: What Are The Best Companion Plants For Radishes

Radishes are one of the quickest producers, often garnering a crop in three to four weeks in spring. Later strains provide roots in six to eight weeks. These plants are tolerant of interplanting provided they are not shaded out by taller species. Many crops make excellent companion plants for radishes, filling in after the roots have been harvested. Installing plants that grow well with radishes can maximize use of the garden bed while harnessing the unique repellent properties of the pungent radish.

Plants That Grow Well With Radishes

Companion planting has been practiced for centuries and was a common Native American practice illustrated perfectly in the “three sisters” method of cropping where corn, squash and beans were planted to support each other, enhance nitrogen, utilize space and shade weeds. Each plant has something to offer the other and radish companion plants can fulfill the same needs. Planning is a key feature in intercropping where space, size, growing conditions and nutrient needs are all considered for a seamlessly compatible garden.

Due to the radish’s quick production and ability to be serial planted, other plants that grow more slowly and need a longer season to produce can be used to complete the garden bed. As long as the radish crop isn’t severely shaded, these little roots will grow at the feet of many species of plant.

Peas and leaf lettuces are started in early spring as soon as soil is workable. This is also the time to sow radish seeds. The slower growth of the peas and lettuce allows radishes to develop without serious interruption, with harvest time well before the other two vegetables.

Plants which will not be ready for many months, such as tomatoes and peppers, can also be intercropped with the earlier radish harvest.

Other Radish Companion Plants

Radishes will also help repel cucumber beetles, which means cucumbers, with their long growing season requirements, are also good companion plants for radishes.

Plants that help radishes might be strong smelling herbs, nasturtium, and species in the allium family (such as onions).

Pole beans and sweet peas, which rise high above the garden on stakes, help fix nitrogen in soil and enhance production while juicing up the soil for other high nitrogen feeders like lettuces.

Be cautious when planting near brassicas (like broccoli), however, as radishes can attract flea beetles, which will damage this plant’s leaves. Hyssop is also not compatible with radishes.

Considerations for Radish Companion Planting

As you plan your garden and want to incorporate radishes, consider some issues. First, are the seeds spring, summer or winter forms?

  • Early season radishes will be best combined with early season vegetables or those that will not get too large in a few weeks to compete with the low growing roots.
  • Summer varieties take longer to mature and should be installed where sunlight will reach them for up to eight weeks. This negates certain of the larger, long season crops as radish companions.
  • Winter cultivars need a longer period as well but can be installed with late season plantings of spinach, kale and other leaf crops.

Depending upon your season, you may also get another crop of the cool weather darlings such as snow and snap peas.

Radishes also have attractive foliage in many cases and are useful in annual beds and borders as visual companions to flowers and herbs.

Intercropping Radishes

“Companion Planting is the growing together of all those elements and beings that encourage life and growth; the creation of a microcosm that includes vegetables, fruits, trees, bushes, wheat, flowers, weeds, birds, soil, microorganisms, water, nutrients, insects, toads, spiders, and chickens.” – John Jeavons, How to Grow More Vegetables Than You Ever Thought Possible

Radishes serve as a general aid in repelling many insects and draw aphids, Flea Beetles, and some other pests away from peppers, squash, and cucumbers.

Planting radishes in a bed that hosted a cole crop in the last three years under some circumstances is not advisable. Cole crops are cool weather brassica and mustard family plants. Radish is closely related to these plants and shares many of the same problems. Although they shouldn’t go in succession with one another, there are circumstances when there are advantages to inter-cropping them.

The primary problems inflicted on radishes by cole crops is cabbage Root Maggot, If you’ve had problems with this in the past keep them apart. Beneficial Nematodes are very effective in controlling root maggots. Incorporating wood ash into the soil also helps to prevent the occurrence of root maggots.


Radish can be planted with carrots , the radish will mature very quickly and loosen the soil for the carrot seeds as they germinate. The radishes will already be harvested when the carrots are still in pampers.

This same scenario works with other root crops such as beets , parsnip and even legumes.


Radish and peas can be inter-planted. The radish will deter some of the pests that feed on peas.

Lettuce interplanted with radish seems to make radishes more tender, radish which matures much quicker than lettuce will help lure early season pests away, flea beetles in particular.



Radish, Raphanus sativus, is an herbaceous annual or biennial plant in the family Brassicaceae, grown for its edible taproot. The radish plant has a short hairy stem and a rosette (ground level horizontal and circular leaves) of oblong shaped leaves which measure 5–30 cm (2–12 in) in length. The top leaves of the plant are smaller and lance-like. The taproot of the plant is cylindrical or tapering and commonly red or white in color. The radish plant produces multiple purple or pink flowers on racemes which produce 2–12 seeds. The reddish brown seeds are oval, and slightly flattened. Radish is generally grown as an annual plant, surviving only one growing season and can reach 20–100 cm (8–39 in) in height depending on the variety. Radish may also be referred to by the name of the cultivar and names may include Chinese radish, Japanese radish or oriental radish. The origin of the radish plant has not been determined but they are found growing native from the Mediterranean to the Caspian Sea.

The radish root can be eaten fresh in salads or cooked with other ingredients such as meat. The leaves of the plant are also edible and can bu used as a salad green.


Basic requirements Radishes are fast growing cool-season vegetables that grow very well in cool moist climates. the optimum temperature for the growth of radishes is between 10 and 18°C (50–65°F) and they grow best in a well-draining sandy loams which are rich in organic matter with a pH between 5.8 and 6.8.. Radish should be grown in full sun to part shade. Propagation Radish is propagated directly from seed into a prepared bed. Seeds should be planted in late winter to early spring for the first spring crop and plantings can be staggered to provide a continuous harvest. A small amount of nitrogen may be applied to the soil prior to planting (up to 60 kg per hectare). Seeds should be planted at a depth of 1 cm (0.5 in), allowing 2.5 cm (1 in) between individual plants and a further 30 cm (12 in) between rows. Commercial producers may drill seeds using planting rates of 30–40 kg per hectare. General care and maintenance Radishes will benefit from the addition of small amounts of nitrogen fertilizer at regular intervals spaced over the growing season. Seedlings should be kept uniformly moist as they develop, but not wet. Weeds should be carefully removed from around the plants. Harvesting Radishes usually reach full maturity between 30 to 50 days after sowing. They should be harvested promptly as over-mature radishes become woody and develop a bitter taste. The plants may be topped by cutting back the leaves to a height of 7–10 cm (2.8–3.9 in) prior to harvesting, or whole plants can be pulled from the soil. Roots should be washed prior to storing to increase longevity.
