Apple 'Cox's Orange Pippin' problems — and how to fix them
Apple 'Cox's Orange Pippin' (Malus domestica 'Cox's Orange Pippin') 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.
Apple scab
Cox is highly susceptible: dark leaf blotches and scabby fruit in wet seasons. Choose a warm, airy site, remove fallen leaves, and prune for good airflow.
Apple canker
Sunken, cracked bark that girdles and kills branches, worse on cold, wet soils. Cut out cankers back to clean wood, improve drainage, and avoid wounding the bark.
Powdery mildew
White coating on shoots and leaves. Prune out silvered, infected tips in winter and keep young trees from drying out.
Fruit drop and poor set in cool sites
Cox sets and ripens poorly in cold, shaded gardens. Plant in the warmest sheltered spot, ensure a compatible pollination partner, and consider wall training.
