Slugs and Snails

Slugs and snails are common pests that feed on the foliage of Campanula poscharskyana. They create irregular holes in the leaves, and slime trails can be visible. Heavy infestations can defoliate the plant.

Steps:

    • For division, dig up the plant in early spring or fall.
    • Carefully separate the root mass into smaller sections, ensuring each section has roots and shoots.
    • Replant the divisions in well-drained soil.
    • Take stem cuttings in spring or early summer.
    • Remove the lower leaves from the cutting.
    • Dip the cut end in rooting hormone (optional).
    • Plant the cutting in a pot with moist potting mix.
    • Keep the soil consistently moist until roots develop.

Diatomaceous Earth

To control slugs and snails, apply diatomaceous earth around the base of the plant.
