Top Companion Plants for Thornless Blackberries
1. Nasturtiums
Nasturtiums are vibrant and easy to grow, making them an excellent companion for blackberries. They attract aphids away from the berries and can also repel whiteflies and beetles. Their trailing habit helps cover the soil, reducing weeds and conserving moisture.
2. Borage
Borage is a beneficial herb that attracts pollinators like bees and butterflies. It also repels pests such as tomato hornworms and cabbage worms. Borage’s edible leaves and flowers add flavor to salads, making it a dual-purpose plant in your container garden.
3. Marigolds
Marigolds are renowned for their pest-repelling properties. They emit a scent that deters nematodes, aphids, and beetles. Their bright blooms also add a splash of color to your container garden, creating an inviting landscape.
4. Chives
Chives are a low-maintenance herb that can help repel aphids, Japanese beetles, and other pests. They also attract beneficial insects, such as pollinating bees, which are vital for fruit production. Chives can be planted in the same container as blackberries for convenience.
5. Clover
Clovers, especially microclover, are excellent ground cover plants that fix nitrogen in the soil. They help improve soil fertility and maintain moisture levels. In container settings, clovers can be used as a living mulch around blackberry plants.
