Best Companions

Marjoram, Corn

Marigolds, Alliums

"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 PossibleHow to Grow More Vegetables, Eighth Edition: (and Fruits, Nuts, Berries, Grains, and Other Crops) Than You Ever Thought Possible on Less Land Than You ... (And Fruits, Nuts, Berries, Grains,)

Good candidates to companion plant with peppers include Corn, Onions, garlic and Alliums, Marigolds, Carrots, Parsnips, Beans

Bad candidates to companion plant with peppers include cabbage and cabbage family plants, fennel

Onions

Intercropping of Alliums, in particular Onions and Garlic has been demonstrated to have substantial impact on pest populations.Aphids and other sap sucking green flies and their maggot offspring, leafhoppers and bean beetles were repelled from the pepper crops. [1]

A 1990 study compared inter-plant cropping systems over consecutive seasons. Interplanting Onions with pepper produced yield increases of 36% -59% [2]

Garlic - Leeks - Chives.

Garlic is a natural insect repellent it releases odors that are proven to deter many insects and people as well, it also releases sulfur into the soil which serves as a natural fungicide. Studies with related alliums, leeks and chives have shown that the odor they give off repels aphids which is great for hot / chile peppers which actually emit an odor that attracts aphids.

Beans

Once again, contrary to popular belief beans and peppers can and do have a symbiosis when inter-planted. Chile peppers will actually produce higher yields when interplanted with beans than when grown alone.


















In 1987 another study found that pepper and soybean interplanted in alternating rows increased the vitality of pepper plants - the leaf water potential of pepper plants intercropped with soybean was greater than that of pepper plants grown by themselves. [3]

In 1998 another study concluded that beans planted along with peppers produced higher pepper yields but slightly lower bean yields [4]

Corn

In addition to its obvious ability to provide shade it is documented that corn will help protect against aphids, and reduce the incidence of plant disease in peppers.

Shading Pepper Plants

Foodscaping: Practical and Innovative Ways to Create an Edible Landscape Paperback – May 6, 2015

Hot peppers are a tad confusing. There are at least 100 varieties that will readily cross-pollinate. Another oddity is that when hot peppers are grown in a stressful or very hot environment, the acids in the fruit accumulates and you get a much hotter pepper. In moderate climates it tends to be a kinder gentler pepper.



Excessively hot weather can also cause peppers to drop their blossoms, and-or fruit, so providing some shade is helpful - not full shade just some shade.

Many hot pepper varieties benefit from being inter-planted with companions that will provide a partial shading and wind break. Plants that provide this amicably are ...

Lovage - Interplanting benefits to peppers is limited to shading and wind protection where needed. It is believed to improve the vitality and the flavor of many garden vegetables although this is undocumented.

Marjoram - A low growing herb is believed to improve the vitality and the flavor of many garden vegetables. The flavor enhancement aspect is undocumented but so far as increasing the vitality of peppers - yes marjoram certainly does. Pepper plants thrive on high humidity - not dry hot heat - Marjoram works well as a living mulch / ground cover in retaining moisture and hence humidity. It is non-competitive with peppers and there are no antagonistic interactions.



Marjoram is a hardy and versatile plant that doesn't require a lot of fertilizer. Maintain the proper pH range and Marjoram will basically take care of itself.

Basil will also work in the same fashion as Marjoram , but is somewhat competitive. Basil is also said to enhance the flavor of peppers - once again taste is in the mouth of the beholder.

Eggplant - close relative of peppers, can be inter-planted with peppers in moderation, in excess it will add to the attracability to insects. Eggplant has successfully been used as a trap crop for aphids in commercial operations, although I woldn't recommend this to home gardeners as sacrificing your eggplants to protect the peppers doesn't seem like a winning proposition. Instead, Try using Radishes - they are quickly maturing, and will lure flea beetles away from susceptible plants. The damage flea beetles can do to radish will not be as devastating.

Even if you loose a few radish plants - C'est la vie.

Grow Tomatoes -close relatives of peppers, can be inter-planted with peppers in moderation, in excess it will add to the atractability to insects.

Okra - another close relative of peppers, can be inter-planted with peppers in moderation, in excess it will add to the attract ability to insects.

Swiss chard / chard - Inter-planting benefits to peppers is limited to shading, wind protection where needed, some weed suppression.

Marigolds won't provide much shade, but they are good companions to pepper plants. They release a substance into the soil that deters nematodes and some other micro-organisms that are harmful to plants. Do not expect to see immediate results when planting them, the compound needs to accumulate for several season before it becomes highly effective.

Carrots inter-planted with peppers will work for the shading/mulch effect of the carrots on the peppers. Peppers are also members of the nightshade family and secrete a natural insect deterrent called solanine which eliminates many insects that are harmful to carrots. Peppers are not as good as tomatoes for their solanine content but they are helpful.



Avoid Fennel which is allelopathic to most garden plants. It exudes compounds designed by nature to eliminate competing plants from its immediate area. Dill is one of the few garden crops that can be grown with it.

Pest Suppression

Please keep in mind that many inter-actions are also percentage based. If an insect that attacks a certain garden plant is repelled by another type of plant - that doesn't mean that absolutely no insects of the genus in question will go near the plants in question - it simply means a much lower percentage than normally would have attacked the plant will show up.

Comfrey leaves are recommended to prevent scab - this is unproven
