Troubleshooting
Hardy pear problems — and how to fix them
Hardy pear (Pyrus communis 'Beurré Hardy') 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.
Biennial bearing
Beurré Hardy has a tendency to crop heavily one year and poorly the next. Thin fruit to one per spur cluster in high-crop years to encourage a more consistent annual yield and maintain tree vigour.
Pear scab (Venturia pirina)
Dark scabby lesions on leaves and fruits, most severe in cool, wet springs. Remove fallen leaves in autumn; prune for airflow; apply copper or myclobutanil fungicide from green-cluster stage if pressure is high.
Fireblight (Erwinia amylovora)
Beurré Hardy shows moderate susceptibility. Affected shoots blacken and wilt. Prune well below the lesion; sterilise tools; burn cut material. Avoid soft, nitrogen-driven growth during the growing season.
