- Spinach – contains the compounds known as saponins, which repel pests
- Spring Onions – strong smell repels pests
- Chives – strong smell deters pests. Chives add potassium and calcium to the soil through their chopped-and-dropped leaves.
- Basil – wards off aphids and mites.
- Thyme – deters worms.
- Catnip – discourages insects as aphids and cabbage loopers — both enemies of the strawberry.
- Yarrow – attracts pollinators
- Comphrey – conditions the soil. Leaves can be used to mulch and feed nitrogen to the soil.
- Borage – repels pests and attracts predatory insects and pollinators. Improves the flavour of strawberries.
- Bush Beans – repels some beetles and hosts nitrogen-fixing bacteria which serve to fertilize the soil for better strawberry yields.
- Caraway – attracts parasitic wasps and parasitic flies that are voracious predators of many common strawberry pests.
- Lupin – This flower is actually a legume. Like the beans mentioned above, it also fixes nitrogen in the soil, thereby fertilizing for surrounding plants, including strawberries. It also attracts honeybees.
Avoid planting strawberries near members of the Cabbage family. The cabbage family plants will have their growth impaired by strawberry plants close by. The major members of the cabbage family include:
- Brussels sprouts
- Chinese broccoli
- collard greens
- Romanesco broccoli
The most common of these plants are:
If these plants (or melons, okra, mint, bush or bramble fruits, stone fruits, chrysanthemums, and roses) have been grown in the same spot recently (within 5 years), it is best to grow your strawberry plants elsewhere.
