  Leeks are another allium that makes a great radish companion plant. Plant leeks to protect radishes and other vegetables from aphids, slugs, cabbage worms, and other predator insects.

  • Name:Leek (Allium ampeloprasum)
  • USDA Hardiness Zones:5-9
  • Light:Full sun
  • Soil:Loamy, well-drained

  Lettuce

  

  When planted together with lettuces, radishes tend to be more tender and juicy. Radishes help break up compacted soil, creating the loose soil environment that lettuce thrives in.

  • USDA Hardiness Zones:2-11
  • Light:Full sun, partial sun
  • Soil:Loamy, rich, well-drained

  Peas

  

  Peas are a great companion plant for radishes. They add nitrogen to the soil, which helps the root vegetable thrive. Because they are climbing plants, peas don't compete for the same space. And like radishes, peas can be planted as soon as the soil is workable.

  • Name:Pea, garden pea (Pisum sativum)
  • USDA Hardiness Zones:2-11
  • Light:Full sun, partial sun
  • Soil:Moist, well-drained

  Dill

  

  Dill is a useful herb to plant, as it attracts beneficial insects such as ladybugs, bees, butterflies, and parasitic wasps to your garden. Radishes and dill thrive in the same temperatures and environment.

  • Name:Dill (Anethum graveolens)
  • USDA Hardiness Zones:2-11
  • Light:Full sun
  • Soil:Rich, well-drained

  Mint

  

  The many types of mint all have one thing in common: they are great at repelling flies, fleas, and spiders in the garden. When planted near radishes, mint can also help deter grazing animals like deer.

  • Name:Mint (Mentha spp.)
  • USDA Hardiness Zones:3-11
  • Light:Full sun, partial sun
  • Soil:Loamy, moist, well-drained

  Oregano

  

  Radishes grow very well beside perennial herbs like oregano, which attracts ladybugs to the garden. Oregano's powerful aroma helps repel cabbage moths, which feast on radishes and other Brassica species such as cabbage and broccoli.

  • USDA Hardiness Zones:4-10
  • Light:Full sun
  • Soil:Well-drained

  Spinach

  

  Both radishes and spinach can be grown in the cooler temperatures of spring and autumn, and work well when interplanted. As radish bulbs grow, they help break up tough soil, making room for spinach roots to grow. Most pests prefer to munch on radish greens, luring them away from the delicate spinach leaves.

  • Name:Spinach (Spinacia oleracea)
  • USDA Hardiness Zones:2-11
  • Light:Full sun, partial sun
  • Soil:Loamy, moist, well-drained

  Common Beans

  

  Beans and other legumes grow well with most herbs and vegetables. Beans fix nitrogen in the soil, providing radishes and other nearby plants with an essential nutrient. And because beans tend to bush or climb, they don't compete with radishes for the same soil space.

  • Name:Common bean, green bean, snap bean, string bean, French bean (Phaseolus vulgaris)
  • USDA Hardiness Zones:2-11
  • Light:Full sun
  • Soil:Loamy, moist, well-drained

  Nasturtium

  

  Nasturtiums, a type of edible flower, attract aphids. While it might seem counterintuitive to introduce a plant that attracts pests, having nasturtium in your garden will lure the insects to the flower and away from your other crops, including radishes.

  • Name:Nasturtium (Tropaeolum spp.)
  • USDA Hardiness Zones: 9-11
  • Light:Full sun
  • Soil:Moist, well-drained

• 12 of 15

  Cucumbers

  

  Radishes help to repel cucumber beetles, which feed on the leaves of cucumber plants. Cucumbers also work well with radishes because they don't compete for space; radishes grow beneath the soil whereas cucumbers grow above ground.

  • Name:Cucumber (Cucumis sativus)
  • USDA Hardiness Zones:2-11
  • Light:Full sun
  • Soil:Moist, well-drained

  • USDA Hardiness Zones:3-10
  • Light:Full sun to part shade
  • Soil:Loose, well-drained

  • USDA Hardiness Zones:2-11
  • Light:Full sun
  • Soil:Moist, well-drained
