Apple 'Honeycrisp' problems — and how to fix them

Apple 'Honeycrisp' (Malus domestica 'Honeycrisp') 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.

Bitter pit

Sunken brown spots in the flesh from localised calcium deficiency, to which Honeycrisp is notably prone. Maintain even soil moisture, avoid heavy nitrogen, and don't over-thin to oversized fruit.

Biennial bearing

Heavy crops one year, almost none the next. Thin fruitlets in early summer to one or two per cluster to even out cropping year to year.

Apple scab

Olive-brown blotches on leaves and corky lesions on fruit in wet springs. Rake and remove fallen leaves, prune for airflow, and choose an open, sunny site.

Codling moth

Grubs tunnelling into the core. Use pheromone traps to monitor and time controls, and hang cardboard bands or remove damaged fruit to break the cycle.
