What's eating my ice plant?

Ice Plant (Sedum spectabile) grown outdoors attracts aphids and is browsed by deer and rabbits. Slugs and snails may target young growth in damp conditions. The dense flower heads also draw vine weevils whose larvae chew roots. Aphids are the most reliably recurring threat, clustering on new stems and flower buds.

Soft colonies of green, black, or grey insects on new stems and flower buds; sticky honeydew residue and distorted growth. Blast off with a strong jet of water; apply insecticidal soap or neem oil spray; encourage ladybirds and lacewings as natural predators.

Irregular notched leaf margins from adult feeding at night; wilting and plant collapse from C-shaped larvae eating roots through the growing season. Apply biological control nematodes (Steinernema kraussei) to moist soil in late summer; use a proprietary vine weevil drench; check under pots for white grubs.

Irregular holes and slime trails on succulent leaves and young stems, worst after rain. Set beer traps; apply copper tape around containers; use wildlife-safe iron phosphate pellets; remove hiding spots nearby.

Stems and flower heads browsed to the ground overnight, especially in autumn when flowers are in full bloom. Physical barriers (wire mesh or fencing) are the most reliable solution; deer-repellent sprays offer temporary deterrence and need re-application after rain.
