European Hazel 'Witchford' problems — and how to fix them
European Hazel 'Witchford' (Corylus avellana 'Witchford') 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.
Needs a pollination partner
Largely self-incompatible like other hazels; reliable heavy crops require a compatible second variety with overlapping flowering nearby.
Squirrels and nut weevil
Grey squirrels raid nuts before ripening and weevil larvae infest kernels. Harvest as nuts mature, net vulnerable bushes, and clear fallen infested nuts.
Suckering and congestion
Vigorous basal suckers and crowded old wood reduce cropping. Remove suckers and renewal-prune on a multi-year rotation to keep fruiting wood productive.
Powdery mildew and leaf spot
Damp, still conditions encourage powdery mildew and bacterial leaf spotting. Maintain an open centre and water at the base for good airflow.
