The reason companion planting is so beneficial is not fully understood, but has been noted by farmers and gardeners for many generations. There are some basic concepts that do make good sense. The physical structure of companion plants with tall strong stems may protect your chile plants from wind damage. The root growth of companion plants with deeper root systems can improve the overall health of the compacted soil by opening up channels for better drainage and air exchange. The production of chemical and aromatic compounds can repel insect pests and deter animal foraging too.
Here is a list of companion plants that are known to benefit peppers:
Basil wards off thrips, flies and mosquitoes. Parsley blossoms attract beneficial predatory wasps that feed on aphids. Marjoram, rosemary and oregano seem to have a helpful effect on peppers. Dill is said to both attract beneficial insects and repel pests. Chives also make great companion plants for peppers.
Tomatoes deter soil nematodes and beetles. Carrots, cucumbers, radishes, squash, and onions and garlic do well when grown in close to peppers.
Spinach, lettuce and chard help crowd out weeds due to their short stature and rapid maturation. Beets and parsnips can fill in space and retard weeds as well as keep the soil cool and moist. Corn serves as a windbreak and sun barrier. Beans and peas fix nitrogen into the soil, a necessary nutrient for peppers, and also help block wind and sun. Buckwheat can be grown around pepper plants to attract pollinators.
Chile plants don’t like the company of every plant, so avoid planting peppers with fennel or near members of the Brassica family, including cabbage, broccoli, cauliflower, and mustards.
Here in our garden, we have planted cucumbers, eggplant, okra, squash and basil, parsley, oregano and rosemary alongside the chile plants. Adding companion plants to your garden creates a diverse mixture of plants and can provide many benefits for your pepper plants.
