Troubleshooting
Tayberry problems — and how to fix them
Tayberry (Rubus fruticosus × idaeus 'Tayberry') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Raspberry beetle
Larvae feed inside ripening berries near the stalk end. Hang traps and cultivate the soil beneath plants in winter to reduce overwintering larvae.
Grey mould (botrytis)
Fruit rot in wet summers, worse where canes are crowded. Train canes spaciously, pick promptly and remove any rotting fruit.
Frost damage to early flowers
Early blossom can be caught by late spring frosts in cold gardens, reducing the crop. Site away from frost pockets or fleece flowers on cold nights.
Cane spot
Purple-bordered lesions on canes weaken growth and yield. Cut out and destroy affected canes and avoid wetting foliage when watering.
