Troubleshooting
Doyenné du Comice Pear problems — and how to fix them
Doyenné du Comice Pear (Pyrus communis 'Doyenné du Comice') 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.
Poor pollination and light crops
Comice is self-sterile and can crop shyly. Plant a compatible group-4 pear nearby and choose a warm, sheltered spot to encourage good blossom set.
Fruit cracking and russeting
Skin cracks and rough russet patches follow uneven watering and weather swings. Keep soil moisture steady and mulch to buffer dry spells.
Pear scab
Dark scabby blotches on fruit and leaves in wet springs. Rake fallen leaves, prune for airflow and remove cankered shoots.
Fireblight
Blackened, shrivelled shoots that look scorched, where present in your region. Cut well below affected wood into healthy growth, disinfecting tools between cuts.
