Discover companion plants that repel pests naturally and protect your garden. Learn the best pest-control plant pairings for healthier crops and gardens easily
PEST & PLANT CARE
One of the easiest ways to reduce garden pests without using chemical pesticides is through companion planting. Certain plants naturally repel insects, attract beneficial pollinators, and improve the overall health of your garden.
Companion planting has been used for centuries by gardeners who wanted healthier crops, better harvests, and fewer pest problems. By strategically placing certain flowers, herbs, and vegetables together, you can create a more balanced and productive growing environment.
In this guide, you'll discover the best companion plants that naturally repel garden pests and learn how to use them effectively.
Why Companion Planting Works
Many insects locate plants through scent.
Strong-smelling herbs and flowers can:
Mask the scent of vegetables
Repel unwanted insects
Attract predators that feed on pests
This creates a natural defense system that reduces the need for sprays and pesticides.
What Is Companion Planting?
Companion planting is the practice of growing specific plants together to benefit one another.
Benefits include:
Repelling harmful insects
Attracting beneficial insects
Improving pollination
Enhancing soil health
Maximizing garden space
Increasing harvest yields
Many companion plants release natural scents that confuse or deter pests before they can damage your crops.
Grow basil beside tomato plants for a classic companion planting combination. It may help deter pests while providing fresh herbs for your kitchen.
Plant marigolds around the borders of vegetable beds to create a natural pest barrier. Their bright flowers also attract pollinators that help improve harvests.
Best Companion Plants That Repel Garden Pests
Tuck garlic between vegetable rows to naturally discourage aphids and mites. As a bonus, you'll harvest flavorful garlic bulbs at the end of the season.
Always grow mint in containers, even in garden beds. Its powerful pest-repelling scent is beneficial, but its roots can quickly spread and take over your garden.
Plant chives near tomatoes, carrots, and roses to create a natural pest barrier while attracting pollinators that support healthier blooms and harvests.
Plant lavender near garden entrances, pathways, or vegetable beds. Its soothing fragrance attracts pollinators while naturally discouraging mosquitoes and moths.
Nasturtiums are one of the best companion plants because they sacrifice themselves to save your vegetables by drawing aphids and whiteflies away from crops.
Let a few dill plants flower instead of harvesting them all. The blooms attract ladybugs and lacewings that naturally help control aphids and other garden pests.
Calendula is one of the easiest flowers to grow in a vegetable garden. Its cheerful blooms attract beneficial insects while helping keep aphids and whiteflies under control naturally.
Plant rosemary around cabbage, broccoli, cauliflower, and carrots to create a fragrant natural barrier that helps discourage pest insects while attracting beneficial pollinators.
Attract Beneficial Insects
Useful for controlling fungal problems while discouraging certain pests.
Not all insects are harmful.
Helpful insects include:
Ladybugs: Feed on aphids and soft-bodied pests.
Lacewings: Consume aphids, mites, and whiteflies.
Hoverflies: Excellent predators of aphids.
Bees: Improve pollination and harvest yields.
Flowers such as dill, calendula, and lavender attract these valuable garden helpers.
