Troubleshooting
Campanula punctata problems — and how to fix them
Campanula punctata (Campanula punctata) 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.
Invasive spread
Rhizomes and runners can colonise quickly. Lift and divide, install a root barrier, or site where it can roam freely.
Slug and snail damage
Tender young shoots are a favourite. Protect emerging growth in spring with traps, barriers or wildlife-safe controls.
Rust and powdery mildew
Orange pustules or white film in damp, crowded plantings. Improve spacing and airflow and remove affected leaves promptly.
Leaf scorch in dry soil
Crisped margins follow drought. Keep the root zone cool and moist with mulch and consistent watering through summer.
