Companion Plants for Peppers: Cultivate Prosperous Peppers With Garden Friends

With temperatures soaring, brighter evenings, and longer days, summer is right around the corner. What's better than welcoming the season with some fresh new plants for your garden? Summer is the ideal growing season for pepper plants.  Just like humans, peppers long for companionship. Well, not really, but peppers do grow better when they have companion plants near them.

Pepper plants are an extremely popular vegetable to plant, and we can see why. There are hundreds of varieties, ranging from hot peppers to sweet peppers, and everything in between. Peppers thrive with lots of time spent in the sun-- 6-8 hours a day to be exact. They also love to climb up a trellis or grow in raised beds, depending on the species. Peppers share the nightshade family with tomato plants, making them a common vegetable.

Summer is synonymous with grilling and there's not much better than grilled peppers and veggies. Growing your own is not only a labor of love, but can produce much tastier results than the store bought equivalent.

What is Companion Planting?

A gardening hack for producing successful plants is companion planting. According to Treehugger, "Grouping complementary plants (companion plants) together in the garden to benefit each other, can be done for a variety of reasons, such as to provide shade or a wind barrier to other plants, or to cover the surface of the soil with edible plants to crowd out weeds, or even to help boost the growth, flavor, or yields of food crops."

It's a win-win for any gardener who wants to grow peppers while filling up their vegetable garden with other delicious plants. Growing plants together and using trap crops can help keep away pests like bean beetles and hornworms, among others. Common companion plants include marjoram, allium, borage, kohlrabi, legumes, and even parsnips and turnips.

Leeks, which are part of the onion family, are a good companion plant due to their small growing space. They fill in the bare areas of the garden, without overtaking other plants. Leeks also a great repellent for pesky carrot flies.

11. Beans

Planting beans, specifically pole beans helps fix nitrogen in the soil. This aids in the growth of the peppers and the other plants in the garden. Bean plants can also add some much needed shade.

12. Swiss Chard

This leafy green protects the peppers from wind and sun. It also makes a great salad base.

13. Buckwheat

A lesser known plant, buckwheat's main job is to attract pollinators to the garden.

Dried oregano is a household staple, and fresh oregano is even better. This herb doesn't take up much space, and makes a great filler.


Whether you love it or hate it, okra is the perfect companion for peppers. It provides shade, and keeps the aphids away.

Keep Your Peppers Thriving

Not all insects founds in the garden are a death sentence to plants. Ladybugs are beneficial insects you'll want around. Aside from being cute, they survive by eating aphids. Since aphids love to attack peppers, you'll want to keep ladybugs around as a natural repellent.
