Growing strawberries with the right companion plants can enhance flavor, repel pests, and improve soil health. This guide reveals the top companions like borage, spinach, and thyme that create a thriving garden ecosystem.
If you’ve ever bitten into a sun-warmed, juicy strawberry fresh from your garden, you know the joy of homegrown fruit. But did you know that planting strawberries alongside the right neighbors can make them even sweeter, healthier, and more productive? Companion planting is a time-tested gardening technique that pairs plants to support each other’s growth, deter pests, and improve soil conditions. When it comes to strawberries, choosing the best companions can transform your patch from average to amazing.
Strawberries are shallow-rooted perennials that thrive in well-drained, fertile soil and full sun. While they’re relatively easy to grow, they’re also vulnerable to pests like slugs, aphids, and spider mites, as well as fungal diseases. That’s where companion plants come in. By selecting the right plants to grow nearby, you can create a balanced garden ecosystem that naturally reduces problems and boosts yields. From herbs that repel insects to leafy greens that act as ground cover, the right companions make all the difference.
Key Takeaways
- Borage boosts strawberry flavor and deters pests: This herb improves growth and repels tomato hornworms and cabbage worms.
- Spinach acts as a living mulch: It conserves moisture, suppresses weeds, and grows well in strawberry beds.
- Thyme repels harmful insects: Its strong scent deters whiteflies, cabbage loopers, and other garden pests.
- Marigolds prevent nematodes and attract pollinators: These colorful flowers protect roots and bring in beneficial insects.
- Avoid planting strawberries near potatoes or tomatoes: They share diseases like verticillium wilt that can harm both plants.
- Companion planting improves soil health: Legumes like bush beans fix nitrogen, enriching the soil for strawberries.
- Use low-growing plants to maximize space: Lettuce, chives, and garlic grow well beneath strawberry plants without competing.

Why Companion Planting Works for Strawberries
Companion planting isn’t just folklore—it’s based on real plant interactions. Some plants release chemicals that repel pests, while others attract beneficial insects like ladybugs and lacewings. Certain companions improve soil structure or add nutrients, creating a healthier environment for strawberries to flourish.
For example, borage is one of the most celebrated strawberry companions. Not only does it enhance the flavor of strawberries, but it also attracts pollinators and repels common pests. Similarly, marigolds release a compound from their roots that deters nematodes—microscopic worms that can damage strawberry roots. These natural benefits reduce the need for chemical pesticides and fertilizers, making your garden more sustainable.
Top Strawberry Companion Plants
When planning your strawberry bed, consider these proven companions that support growth and protect against threats.
Borage: The Flavor Booster
Borage is a must-have in any strawberry patch. This herb produces beautiful blue star-shaped flowers that attract bees and other pollinators. More importantly, studies suggest that borage can improve the size and sweetness of strawberries. It also repels tomato hornworms and cabbage worms, which can sometimes target nearby plants. Plant borage around the edges of your strawberry bed for maximum benefit.
Spinach and Lettuce: Living Mulch
Leafy greens like spinach and lettuce are excellent companions because they grow low to the ground and don’t compete with strawberries for sunlight. They act as a living mulch, shading the soil to retain moisture and suppress weeds. Plus, they mature quickly, so you can harvest them before they interfere with strawberry growth. Try planting spinach in early spring alongside your strawberry plants.
Thyme and Oregano: Natural Pest Repellents
Aromatic herbs like thyme and oregano release strong scents that confuse or repel pests. Thyme, in particular, is effective against whiteflies and cabbage loopers. Plant these herbs between strawberry rows or in nearby containers. They also attract predatory insects that feed on aphids and mites.
Marigolds: The Protective Border
Marigolds are more than just pretty flowers—they’re powerful allies in the garden. Their roots emit alpha-terthienyl, a compound that kills harmful nematodes in the soil. French marigolds (Tagetes patula) are especially effective. Plant them around the perimeter of your strawberry bed to create a protective barrier. Bonus: their bright blooms attract hoverflies, which eat aphids.
Bush Beans and Peas: Soil Enrichers
Legumes like bush beans and peas have the unique ability to fix nitrogen from the air into the soil, thanks to symbiotic bacteria on their roots. This enriches the soil, giving strawberries a nutrient boost. Just be sure to plant them where they won’t shade your strawberries, as these crops can grow tall.
Plants to Avoid Near Strawberries
Not all plants make good neighbors. Some can compete for resources, attract the same pests, or share diseases.
Potatoes and Tomatoes: Disease Risks
Avoid planting strawberries near potatoes, tomatoes, peppers, and eggplants. These plants are all part of the nightshade family and are susceptible to verticillium wilt—a soil-borne fungus that can linger for years. If one plant gets infected, it can easily spread to your strawberries.
Cabbage Family Crops: Pest Overlap
Broccoli, cauliflower, and kale may attract cabbage worms and aphids that could migrate to your strawberries. While some gardeners still plant them nearby with success, it’s safer to keep them in a separate bed.
Fennel: The Garden bully
Fennel releases chemicals that inhibit the growth of many plants, including strawberries. It’s best grown in isolation.
Designing a Strawberry Companion Garden
Creating a thriving strawberry bed starts with smart layout and plant selection.
Use Raised Beds or Containers
Raised beds offer better drainage and soil control, which strawberries love. They also make it easier to group companion plants effectively. In containers, you can grow strawberries with herbs like thyme or chives in the same pot—just ensure there’s enough space and sunlight.
Interplant for Maximum Efficiency
Try interplanting strawberries with low-growing companions like spinach, lettuce, or garlic. This maximizes space and creates a layered garden that’s both productive and attractive. For example, plant strawberries in the center, surround them with marigolds, and fill gaps with chives or thyme.
Rotate Crops Annually
To prevent soil-borne diseases, avoid planting strawberries in the same spot year after year. Rotate with non-related crops like beans or leafy greens. This keeps the soil healthy and reduces pest buildup.
Bonus Tips for a Healthy Strawberry Patch
Even with great companions, strawberries need proper care to thrive.
Mulch with Straw
True to their name, strawberries benefit from a layer of straw mulch. It keeps fruit off the soil, reduces rot, and suppresses weeds. Avoid using hay, which may contain weed seeds.
Water Consistently
Strawberries need regular watering, especially during fruiting. Use drip irrigation or soaker hoses to keep leaves dry and prevent fungal diseases.
Encourage Pollinators
Plant flowers like borage, butterfly flowers, and flowering daisies nearby to attract bees and other pollinators. More pollination means bigger, sweeter berries.
Monitor for Pests
Check plants regularly for signs of slugs, aphids, or spider mites. Handpick pests when possible, or use organic solutions like neem oil or insecticidal soap.
Conclusion
Growing strawberries is rewarding, but pairing them with the right companion plants takes your garden to the next level. From borage that sweetens the fruit to marigolds that protect the roots, these natural allies create a healthier, more productive growing environment. By avoiding incompatible plants and designing your bed with care, you’ll enjoy bigger harvests and fewer problems.
Whether you’re a beginner or a seasoned gardener, companion planting is a simple, sustainable way to boost your strawberry success.
