What's eating my hylotelephium 'autumn joy'?

Hylotelephium 'Autumn Joy' is troubled most by vine weevils, aphids, and slugs in garden settings. Deer and rabbits may also browse the fleshy stems. The plant's succulent foliage makes vine weevil grubs a particularly damaging threat, as root destruction can kill established clumps silently before symptoms show above ground.

Grubs eat roots, causing sudden wilting and plant collapse; adult notches appear on leaf margins Apply pathogenic nematodes (Steinernema kraussei) to moist soil in late summer or autumn; use vine weevil killer drench

Clusters of soft insects on new growth and flower buds; sticky honeydew, distorted shoot tips Blast off with a strong water jet; apply insecticidal soap or neem oil; encourage ladybirds and lacewings

Ragged holes in young foliage and stems, especially after rain; silvery slime trails Apply ferric phosphate pellets around the base; use copper tape on pots; hand-pick at night

Stems and leaves browsed to stubs, often overnight; deer leave ragged edges, rabbits clean cuts Physical barriers (wire cloches, fencing); deer repellent sprays on surrounding plants
