Aphids

Aphids are small, sap-sucking insects that can weaken the plant. Symptoms include distorted leaves, stunted growth, and a sticky substance called honeydew.

Slugs and Snails

Slugs and snails can feed on the leaves and stems of Cerastium fontanum, causing damage to the plant. Signs of infestation include holes in the leaves and slime trails.

Steps:

    • For seed propagation, sow seeds in early spring or fall in a well-draining soil mix.
    • Keep the soil moist until germination, which usually takes about 1-2 weeks.
    • For division, carefully dig up a mature plant and separate the root ball into smaller sections.
    • Replant the divisions in a well-prepared area.
