Companion planting is an age-old gardening practice that involves planting different crops together to improve growth, repel pests, and enhance yield. Strawberries, a beloved fruit in home gardens, benefit greatly from strategic companion planting.
The right companions can boost their flavor, protect against pests, and improve overall plant health. Conversely, certain plants can hinder strawberry growth and should be avoided.
Here’s a quick list of the best strawberry companion plants and the worst.
Best Companion Plants for Strawberries
1. Herbs
Basil
Basil improves strawberry flavor and helps deter pests like aphids and spider mites. It also attracts pollinators, boosting fruit production.
Thyme
Thyme acts as a ground cover, retaining moisture and suppressing weeds. Its strong scent deters harmful insects, making it a great companion for strawberries.
Borage
This herb not only improves the flavor and growth of strawberries but also attracts bees and repels pests like hornworms and Japanese beetles.
Chamomile
Chamomile enhances strawberry plant health by improving soil quality and attracting beneficial insects like hoverflies and ladybugs that feed on aphids.
2. Vegetables
Lettuce
Lettuce has shallow roots that do not compete with strawberries. It provides a living mulch that helps retain soil moisture and suppresses weeds.
Spinach
Spinach grows well with strawberries and does not compete for nutrients. It also provides ground cover, reducing soil erosion and maintaining moisture levels.
Onions and Garlic
Alliums like onions and garlic help repel pests such as aphids, slugs, and spider mites. Their strong scent confuses and deters common strawberry pests.
3. Flowers
Marigolds
Marigolds are well-known for their pest-repelling properties. They help control nematodes in the soil and repel aphids, thrips, and whiteflies, making them excellent companions for strawberries.
Nasturtiums
These flowers act as a trap crop, attracting aphids away from strawberries. They also deter squash bugs and whiteflies while adding color and beauty to the garden.
4. Legumes
Bush Beans and Peas
Legumes fix nitrogen in the soil, improving soil fertility and benefiting strawberries. They also provide light shade, which helps keep strawberries cool during hot weather.
Worst Companion Plants for Strawberries
While some plants improve strawberry health and yield, others can be detrimental. Here are some plants to avoid planting near strawberries:
1. Brassicas (Cabbage Family)
- Cabbage
- Broccoli
- Cauliflower
- Kale
Brassicas can inhibit strawberry growth by competing for nutrients and space. They can also attract pests like cabbage worms that may spread to strawberries.
2. Nightshades
- Tomatoes
- Peppers
- Potatoes
- Eggplants
Nightshades are susceptible to similar diseases as strawberries, including verticillium wilt, which can spread between plants, leading to decreased health and productivity.
3. Fennel
Fennel secretes a chemical that inhibits the growth of nearby plants, including strawberries. It can stunt their growth and reduce yield.
4. Melons and Pumpkins
Large vining plants like melons, pumpkins, and squash can overshadow strawberries, depriving them of sunlight. They also compete heavily for nutrients and water.
Additional Tips for Successful
- Rotate Crops: Avoid planting strawberries in the same spot every year to prevent soil depletion and disease buildup.
- Mulch Well: Use straw, pine needles, or wood chips to retain moisture, suppress weeds, and improve soil health.
- Encourage Pollinators: Planting pollinator-friendly flowers nearby ensures a better fruit set and higher yield.
- Space Plants Properly: Give strawberries and their companions enough space to thrive without competing for sunlight, water, and nutrients.
