Campanula poscharskyana problems — and how to fix them
Campanula poscharskyana (Campanula poscharskyana) 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.
Over-vigorous spread
Runners and self-seeding can colonise paving and beds. Shear after flowering and pull unwanted seedlings to keep it in bounds.
Slugs and snails
Soft spring shoots are a favourite target. Protect emerging growth with barriers or wildlife-safe controls.
Crown rot in wet soil
Waterlogging rots the crown. Plant in free-draining sites and avoid heavy, soggy ground.
Rust or powdery mildew
Possible in crowded, humid conditions. Thin and trim for airflow and clear away affected foliage.
