Bacterial disease
Fire blight
How to recognise it
Shoot tips wilt into a hook shape and turn black as if scorched (apple, pear, quince, hawthorn).
What helps
Cut well into healthy wood, disinfect tools. Notifiable in many regions – inform your plant protection service.
Often a care issue is behind it (watering, light, placement) – the care check in the app helps narrow it down.
