Golden Delicious apple problems — and how to fix them
Golden Delicious apple (Malus domestica 'Golden Delicious') 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.
Russet skin
Golden Delicious is genetically prone to skin russeting (rough, brown patches), exacerbated by high humidity, early-season frost, or oil-based sprays near bloom. While purely cosmetic, it can be reduced by site selection in drier climates and timing sprays carefully.
Apple scab (Venturia inaequalis)
Moderately susceptible cultivar. Olive-brown lesions on leaves and fruit in wet springs. Use preventive fungicide from green-tip; rake and remove fallen leaves. Plant in open, airy positions with morning sun to dry foliage quickly.
Powdery mildew (Podosphaera leucotricha)
White powdery coating on young shoots and leaves in warm, dry-ish conditions. Prune off infected tips; apply sulfur or potassium bicarbonate sprays. Golden Delicious has moderate susceptibility; maintain good airflow.
