Wondering what to plant with your chile peppers to help them thrive?
Flowers, chives, carrots, radishes, squash, Basil, Parsley, Dill, Marjoram, Oregano, Rosemary, cucumbers, eggplant, and onions all do well when grown in close proximity to peppers. Spinach and lettuce are suitable pepper companions because they are low-growing with shallow roots, providing an edible ground cover that helps control weeds. Make sure not to plant things too close to your peppers, so as not to shade or inhibit air circulation – but including lots of flowers, herbs and other vegetables in your garden will help increase your pepper harvest and create a pollinator habitat and healthy ecosystem.

Here are some of our favorite Pepper Plant Companions:
Planting annual and perennial flowers near your pepper patch is a sure way to invite pollinators to your garden, which, in turn, help boost your pepper harvest.
Native plants are particularly helpful, so contact your native plant society in your city or state to find out what flowering plants are native to your region. Native plants are easy to grow as they thrive in each area's natural conditions without extra fertilizers or water – plus the birds, butterflies, and bees thrive on native flowers! Some of our favorite native flowers for our area include Coneflowers or Wild Geraniums.

Homegrown National Park »
Good flowers to grow around your vegetable garden include:
Marigolds, Nasturtiums, Goldenrod, Black-Eyed Susans, Coneflowers / Echinacea, Penstemons, Alliums, and Geraniums (Geraniums are known to repel Japanese Beetles!)
Of course, with any flowers or plants, make sure not to plant them so close to your peppers that these flowers shade your peppers, as peppers like sun! If you have them nearby, that will be enough.
Attracting Beneficial Insects:
Flowers, herbs and especially native plants attract beneficial insects like Lacewigs, Ladybugs, and Hoverflies, resulting in their incredible pest-eating larvae that devour aphids, caterpillars and other pests of your vegetables.

We like to keep a patch of Nasturtium growing (it reseeds every year if you leave the large seedpods). It's great as the leaves and flowers are edible, it self-sows, and it looks beautiful in the vegetable garden. The bees love Nasturtium, too!
This slightly over-planted pepper garden (yes, we do it, too!) still provides an abundant harvest. Note the Nasturtium growing in the top of the photo.
2. Basil: Basil is a wonderful herb for using in all sorts of recipes, and some people say that it boosts peppers flavor if grown nearby, and it also repels pests such as aphids and spider mites. It's beautiful too, and the pollinators love the blooms! We usually let a few basil plants bloom for the pollinators, and trim and harvest our other basil plants to keep them growing vegetation. Basil is also super easy to grow from seed, we even collected seeds from our basil last year and started them with great success indoors in our seed starter trays.
3. Chives: Chives are great to grow as they come back every year (perennial), and they are also said to improve the flavor and boost pepper yields. They are also super charming in the garden with their edible purple blossoms, which the bees also adore!
Did you know that Dill makes a great Trap Crop for Tomato Hornworms?
Hornworm moths prefer dill over the tomatoes so having lots of dill growing in your garden will keep these pests away from your precious tomato plants. Did you know that hornworms turn into sphinx or hawk moths, also known as hummingbird moths? Yes, those ones that zoom around the garden at dusk and they look like hummingbirds. :) We love them. Plus, our dill is so prolific and self-seeds so much that we really don't mind if these guys munch on it. As long as they don't attack our tomatoes! Dill also attracts ladybugs, and Black Swallowtail butterflies love laying their eggs on it. So if you enjoy these amazing creatures in your garden, invite them to visit with dill! Dill also attracts hover flies, predatory wasps, and other beneficial insects, so we highly recommend growing it!
5. Coriander and Cilantro: These herbs are great to grow next to Pepper plants, cilantro attracts beneficial insects to gardens while simultaneously it discourages pests such as aphids. Planting cilantro in the shade of pepper plants helps cilantro grow into a lush and bushy plant. Plus, don't worry if it bolts and flowers, the flowers are a huge attractant for pollinators and other beneficial insects, plus, you can save the dried seeds and replant for a never-ending source of Cilantro for your salsas and recipes.
7. Onions: Onions are easy to interplant with other vegetables as they don't take up a lot of room, and they help deter common pests such as aphids, slugs, cabbage worms. Plus, they're great for using the greens and bulbs in salsas, green chile stews, and other recipes.
8. Lettuce: You can grow lettuce in small spaces as an edible living mulch. Lettuce can thrive in the shade of pepper plants in the summer.
12. Squash: You can grow squash near peppers, though make sure not to grow them too close or the large squash leaves could shade your peppers. Squash is great to shade and cut down on weeds in the garden.
16. Cucumbers: Cucumbers are also good companion plants to grow with peppers, and who doesn't like spicy pickles? Hot Peppers and cucumbers can combine to make the best pickles you'll ever eat.
18. Thyme: Thyme is a super easy to grow herb that is low-growing and is perennial (so it comes back better every year!) It also blooms and attracts pollinators out the wazoo. Plus, it's great with all sorts of recipes! You can even harvest Thyme in the winter months, which makes it's a great winter herb.
19. Rosemary Deters Aphids: Which companion plants affect the performance of green peach aphid on host plants? French researchers tested 12 candidate plants under laboratory conditions, and found Rosemary to be one of the best deterrants! Did you know it's super-easy to propogate Rosemary? Just take a snipping of a young stem and put in water, and it will grow roots within a week or two, then plant in soil! Easy peasy. Read more about their study below:
Want to deter aphids? Plant some rosemary throughout the garden, African and French marigolds work well too. A group of French researchers designed an experiment that tested how effective 12 different companion plants were at deterring aphids from infesting a garden. The researchers set up two rows of pepper plants inside 13 individual growing chambers (there were 12 companion plants treatments and one control treatment with no companion plant), and then placed adult female aphids on each plant. Then, the various companion plants were set in between the two rows of pepper plants and allowed to grow alongside each other. Each day, the scientists would count the number of adult females remaining on the pepper plants, and also the number of neonate nymphs (baby aphids) that were produced by the adult female.
During the 12 day experiment, the scientists found that the aphids were more likely to flee from the pepper plants that were near companion plants. The control pepper plants did not lose any aphids, as the bugs were happy in their companion-plant-free environment. They also found that rosemary, lavender, geranium, African marigold, and French marigold significantly decreased the numbers of aphids being reproduced on the pepper leaves. In the end, rosemary outperformed the other companion plants in both deterring aphids, and lowering their reproduction numbers. The scientists attribute this effect to the VOC, or volatile organic compounds, produced by the plants. The VOCs signal to the aphids that the vegetation in a certain area near companion plants is not suitable for rearing young, so encourages the bugs to search on for more reproduction friendly fields.
It looks like a flat of rosemary will be on the planting list for this spring.
Native Shrubs & Trees for Bees:
You can also plant flowering trees to help the pollinators, early spring-blooming fruit trees are a wonderful first meal for hungry bees when not much else is blooming yet. Native shrubs and trees are best, so ask your local garden center or nursery what native flowers, trees and shrubs would thrive in your yard. Serviceberries, oaks, and other natives can really increase the presence of beneficial insects and pest-eating birds in your yard for a well-balanced ecosystem.
Leave the Leaves!
Rather than strip your garden and flower beds to bare soil over the winter, leave the leaves and even the perennial plant stalks and leaves. By doing this, you create a native bee habitat (most bees nest underground, and mulch helps keep them warm and insulated). Leaving leaves and grass clippings on your garden beds also helps to feed and insulate the soil during the winter months. You'll find that the soil will be rich and moist come spring if you give it a nice thick blanket of mulched leaves and grass clippings. By spring, you'll find that most of the leaves have reduced to near nothing, and you can dig them into the soil to continue to feed for the year. Note: we do usually clear out vegetable plant leaves and stalks at the end of the season, especially if there is any powdery mildew or other diseases or pests.
PLANTS TO AVOID PLANTING WITH PEPPERS:
Use Companion Plants to grow more Peppers
Growing companion plants with Chile Peppers ensures a great harvest! The more different types of plants and flowers you have growing in and around your vegetable and pepper garden, the better your garden will be! While peppers can self-pollinate with wind, having bumblebees, honeybees and other native pollinators give them an extra "buzz" boosts the likelihood of pollination.
