What Is Companion Planting?

Companion plantingis the practice of growing different plants together for mutual benefit. While not all companion planting information is based on hard scientific facts, researchers are studying the observations and garden lore found in farmers’ almanacs.

A garden is a system of biodiversity where all of the plants are connected and interdependent. Sometimes the benefit is one-sided, with one plant selflessly offering partnership advantages to the other. In many cases, the benefit is mutual, with each plant enhancing the other's growth.

Selecting and Planting Companion Plants for Peppers

  • Whether you are transplanting pepper plants and its companions into the garden or growing them all from seed, plan your transplanting and/or sowing so that the plants are in their later growth stages at a similar time.
  • Move the plants to the garden after the danger of frost has passed. Peppers, and their companion plants, need at least six to eight hours of full sun during the growing season. The soil should be well drained and contain organic matter. These plants will also thrive in large containers or raised beds.
  • Be sure to give the plants even and consistent watering of 1- to 2-inches per week. Pepper plants require a lot of water, so using companion plants can help provide mulch and keep the soil cool to help maintain soil moisture.
  • Peppers come in a variety of colors, shapes, flavors, and levels of heat. Bell peppers, Capsicum annuum (Grossum Group), are considered to be "sweet peppers" while the members of Capsicum annuum (Longum Group) include chili peppers and cayenne peppers.Whether you are growing sweet or hot peppers, planting these 8 companion plants can be beneficial in producing healthy, fruit-bearing plants.
  • If you like to grow peppers in containers, group containers containing these plants close together to reap a healthy crop.

What Not to Grow with Peppers

What are the worst plant companions for peppers? Again, avoiding some plants is scientifically based while others are anecdotal.

  • Apricots: If you want to produce quality apricots, do not attempt to grow peppers in containers or locate your garden plot near an apricot tree. A common pepper fungal disease can spread to your apricot tree, ruining fruit production.
  • Brassicas: Almanacs and home gardeners recommend avoiding planting brassicas (cabbage, broccoli, kale, collards, cauliflower)near peppers because they require different soil acidity levels and can deter pepper plant growth.
  • Beans: Beans require a large quantity of nitrogen to thrive and they will "steal" it from the soil and leave pepper plant growth stunted. Vining beans on tall stakes can also deprive pepper plants of sunlight.
  • Fennel: Fennel is also a greedy plant that consumes the nutrients in that pepper plants need to thrive.

Peppers, tomatoes, and eggplants are members of the nightshade family and can be planted together. However, the crops should be rotated in the garden every season. Don’t plant peppers, tomatoes, eggplant, or potatoes in the same garden spot more often than once every three years to help avoid disease.
