Top Picks for Raspberry's Accompaniment (Along with Three to Steer Clear Of)
Raspberries are a delightful addition to any garden, but they require careful consideration when it comes to planting companions. Here's a guide to the best and worst companion plants for raspberries, focusing on pest control, soil enrichment, and disease prevention.
Marigolds, known for their ability to discourage root rot nematodes, are a great choice when worked into the soil at the end of the season. They also attract pollinators and beneficial insects like parasitic wasps and ladybugs that feed on pests in the raspberry patch.
Nasturtiums can be used as a trap crop to attract pests and then destroy the trap crop once a good population of pests has settled into it. They also encourage pollinators and predatory insects to visit the raspberry patch with their bright flowers.
Chives, with their pungent aroma, are an excellent companion for raspberries as they help deter Japanese beetles and other pests. They have the added benefit of taking up little space and being perennials that are cut rather than dug up when harvested. When allowed to flower, chives attract pollinators.
Rue can repel Japanese beetles and some other pests that plague raspberry canes. Yarrow, with its soft, ferny foliage and lovely flowers available in various colours, attracts predatory insects that feed on pests like Harlequin bugs.
White clover acts as a living mulch, suppressing weeds and improving moisture retention in the soil. It also fixes nitrogen in the soil, making it more readily available for raspberry plants. Additionally, it attracts bees and other pollinators when it blooms, making it a good companion plant for raspberries.
However, there are plants to avoid when planning a raspberry patch. Blackberries should not be planted near raspberries due to the risk of sharing viruses and soil-borne fungal diseases. Strawberries should not be underplanted with raspberry canes due to the risk of sharing diseases and pests. Potatoes and other nightshades should be kept at a distance from raspberries due to the risk of spreading blight and verticillium wilt.
It's also important to keep red raspberries separate from black and purple varieties. This is to prevent cross-pollination and maintain the desired characteristics of each variety.
In Germany, garden chrysanthemums, marguerites, and wild carrots are the best companions for rhubarb. They are available as seeds and are compatible with planting near rhubarb for beneficial garden diversity. Late spring flowers like frilled tulips ('Fancy Frills') can complement rhubarb aesthetically in mixed beds or borders.
If a living mulch is desired, consider white clover instead of strawberries. This will not only improve soil health but also attract beneficial insects and suppress weeds.
In conclusion, careful planning and the right choice of companion plants can significantly improve the health and productivity of your raspberry patch while also adding beauty and diversity to your garden.
