What's eating my campanula punctata?

Campanula punctata (spotted bellflower) is especially vulnerable to slugs and snails, which shred leaves and hollow out stems. Aphids cluster on flower buds, and vine weevil grubs can eat roots in containers. Slugs and snails are the number-one threat — use iron phosphate bait and grit mulch around crowns.

Large ragged holes in leaves; hollow stems at ground level; plants collapse suddenly Apply iron phosphate pellets; use beer traps; surround plants with coarse grit or crushed eggshells

Dense infestations on flower buds and shoot tips; honeydew attracts sooty mould Blast off with water; treat with insecticidal soap or neem; encourage ladybirds and parasitic wasps

C-shaped white grubs eat roots, causing sudden wilting; adult notches leaf margins at night Apply pathogenic nematodes (Steinernema kraussei) to moist soil in late summer; use neem-based soil drench
