Carpathian bellflower problems — and how to fix them
Carpathian bellflower (Campanula carpatica) 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.
Crown rot in wet winters
The alpine origin of this species means it is sensitive to waterlogging, especially in winter. Ensure very good drainage at planting time. In heavier soils, incorporate grit and plant on a slight mound. Avoid mulching directly over the crown.
Short-lived without deadheading
Campanula carpatica can be short-lived if allowed to set excessive seed. Regular deadheading prolongs the bloom season and the plant's vigour. Shear the whole plant lightly after the main summer flush to encourage a second wave of flowering.
Slug and vine weevil damage
The compact mound of foliage at soil level is attractive to slugs in spring, and vine weevil grubs can devastate roots in containers. Use a biological nematode soil drench for vine weevil in late summer, and ferric phosphate slug control from early spring.
Prevent carpathian bellflower problems before they start
Most carpathian bellflower issues are care-mismatch, not bad luck. Dial in the basics:
