Companion Plants for Strawberries: Boost Flavor, Health, and Harvests Naturally

Growing strawberries is more than just planting a single row of juicy red fruit — it’s about creating a thriving, interconnected garden ecosystem. One of the most effective ways to support healthier, more productive strawberry plants is by using companion planting. By choosing the right companion plants, you can deter pests, improve soil health, boost pollination, and even enhance the flavor of your strawberries. In this article, we explore the best companion plants for strawberries and how they work together to create a balanced, thriving garden.

Why Companion Planting Matters for Strawberries

Understanding the Context

Strawberries are delicious, versatile, and relatively easy to grow, but they're not immune to pests, diseases, or nutrient-hungry soil. Companion planting offers a natural solution by enhancing resilience and productivity. Beneficial companions can:

  • Repel harmful insects like aphids, nematodes, and spider mites
  • Attract pollinators for better fruit set
  • Fix nitrogen or improve soil structure
  • Act as ground covers to reduce weed competition

Let’s dive into the top companion plants that work beautifully with strawberries.


Top Companion Plants for Strawberries

Key Insights

1. Borage (Borago officinalis)

Borage is often dubbed the “star companion” for strawberries. Its star-shaped blue flowers attract hoverflies and bees, both essential for effective pollination. Moreover, borage releases natural compounds that promote strong growth and improve fruit quality in strawberries.

Why It Works:

  • Enhances fruit size and sweetness
  • Deters hornworms and cabbage moths
  • Adds ornamental value to the garden

How to Plant: Place borage around the edge of your strawberry bed or in mixed containers for easy access by bees.


2. Alliums (Garlic, Onions, Chives)

Members of the allium family produce strong-smelling compounds that repel aphids, thrips, and other pests harmful to strawberries. Garlic and onion plants also help break disease cycles due to their distinct biochemical profiles.

Final Thoughts

Why It Works:

  • Natural pest deterrent without chemical inputs
  • Improves soil resistance to fungal diseases
  • Minimal space competition

Pro Tip: Plant garlic or onions between strawberry rows to protect the entire bed.


3. Marigolds (Tagetes spp.)

Marigolds are a colorful and effective ally in the strawberry patch. Their roots exude a chemical that suppresses nematodes — microscopic pests that damage strawberry roots. Additionally, marigolds attract beneficial insects and add aesthetic appeal.

Why It Works:

  • Protects roots from nematodes
  • Attracts ladybugs and lacewings that eat garden pests
  • Drought-tolerant and easy to grow

Best Practice: Interplant marigolds among strawberry rows or use border rows to maximize protection.


4. Barely (Fassador officinalis) or Spinach

While not traditional companions, low-growing leafy greens like barely (a relative of oats) or spinach provide living mulch that suppresses weeds, retains soil moisture, and cools root zones in summer. Once harvested, they give strawberries room to expand without competing aggressively.

Why It Works:

  • Reduces weed pressure naturally
  • Improves soil moisture retention
  • Short stature avoids shading young strawberry plants

Tip: Plant bear leek or spinach late in spring after strawberry bulbs have started growth, then remove before fruiting season intensifies.
