Kashmir rowan problems — and how to fix them
Kashmir rowan (Sorbus cashmeriana) 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.
Late frost damage to flowers
The early blush-pink flowers are vulnerable to late spring frosts. Site in a sheltered position or avoid frost pockets; severe frost can eliminate the year's berry display.
Fire blight
Wilting, blackened shoot tips indicate bacterial fire blight. Prune well below the lesion with sterilised tools; copper-based sprays at flowering can help prevent infection.
Canker (Neonectria sp.)
Sunken, discoloured patches on bark, causing girdling and dieback. Remove affected limbs; maintain tree vigour through appropriate watering and feeding.
