Radish Companion Planting

Choosing compatible companion plants, especially for your radish plantation, can be a lot of work, but not to worry. The next few lines of this article will sort you out with 20 options for companion planting with radish.

1.  Marigold


Marigolds serve a dual purpose when acting as companions of radish. One, they attract beneficial insects and pollinators, which help the radish bloom. Second, they deter vicious radish pests, so the radish is adequately protected from certain pest infestations.

2.  Rosemary


Bean beetles and carrot flies are terrific pests, and the extent of their negative impact on a radish farm cannot be overstated. However, Rosemary deters these radish pests by its scent, keeping the farm space safe.

3.  Chervil


Aphids are another terrific pest of radishes, and not only are they unforgiving to radishes, but they also infest other farm plants. Chervil is one of the plants that aphids detest; planting chervil with your radish, therefore, keeps your farm safe from aphid infestation. Chervil also improves the flavor of radish.

4.  Eggplant


The presence of eggplants around radishes will create ample shade for the radish to bloom even in hot weather conditions. Radishes return the favor by repelling pests of eggplants away from the cultivation space.

5.  Oregano


Cabbage moths aren’t pests of cabbage alone; they are dreadful pests of radish as well. Oregano has a strong scent that repels cabbage moths, so planting oregano around radish will keep the radish healthy and away from cabbage moth infestation.

6.  Nasturtiums


Nasturtium isn’t directly beneficial to radishes because nasturtiums attract aphids which are severely detrimental to radishes. Most farmers use the strategy of planting nasturtium a little distance from the radish, thereby distracting the aphids away from the radish and shifting their attention to the nasturtiums.

How are you sure the aphids wouldn’t just leave the nasturtiums and infest the radishes? You mean to ask. Well, the nasturtiums have bright blooming flowers that call the attention of the aphids.

7.  Dill


This aromatic herb is a good way of attracting pollinating insects to the radish farm. Dills also attract parasitic wasps, which attack radish pests, thereby keeping pest infestation levels for the radish farm low.

8.  Kale


Kale is one of the plants in the brassica plant family. Kale is a great companion for radishes because it infuses beneficial nutrients into the soil for the use of the radish.

9.  Broccoli

14.  Parsnips


Root maggots and squash vine borers are another pest set that is extremely detrimental to the health and well-being of radishes.

If a better-protected and healthier radish of your goal for companioning, you should definitely go for parsnips.

Pole Bean

Pole Beans are another nitrogen-fixing plant. They help plants cultivated close to them by providing nitrogen into the soil. So, the plants have a better nutrient supply, and this courtesy extends even to radishes.

Planting lettuce with your radish will help keep weeds away from your farm space, as the lettuce will spread its growth to cover the ground, leaving no room for weeds. But aside from this, lettuce keeps the soil moist enough for the thriving of radishes planted as their companions. Not only does lettuce keep moisture within the ground, but it also conserves nutrients within the soil for the use of radish.

20.  Onion


Onions act as pest repellants for radishes and are incredibly fantastic at repelling beetles. Therefore, combining onions and radishes will produce a healthier breed of radishes.

  • Potato, which will not grow well around radish.
  • Cabbage, which requires more nutrients than the same land space, can provide for both radish and itself.
