Troubleshooting
Tulameen Raspberry problems — and how to fix them
Tulameen Raspberry (Rubus idaeus 'Tulameen') 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.
Grey mould (Botrytis)
Soft, fuzzy rot on ripening berries in wet, humid weather. Improve airflow, pick fruit promptly, and remove affected berries to slow spread.
Raspberry beetle
Larvae tunnel into ripening fruit. Cultivate around the base over winter and use appropriate controls at flowering to reduce the dried, maggoty berries at harvest.
Wrong-time pruning
As a summer-fruiting type, it fruits on last year's canes. Cutting all canes to the ground in winter removes the crop; instead remove only the old fruited canes after harvest.
Drought stress
Shallow roots wilt and drop undersized fruit in dry spells. Maintain even moisture and a thick organic mulch through the fruiting period.
