What's eating my hylotelephium spectabile 'brilliant'?

Hylotelephium spectabile 'Brilliant' is most threatened by vine weevil grubs attacking its roots and aphids clustering on succulent new growth. Slugs target emerging spring shoots, and deer may graze plants in open gardens. The robust fleshy stems attract these common garden pests rather than specialist insects.

Invisible root destruction by C-shaped grubs; first sign is sudden wilt or plant lifting cleanly from soil Drench soil with nematodes in late summer; repot container plants and dispose of any grubs found

Soft-bodied insects on stem tips and under leaves; honeydew deposits, distorted growth Spray with insecticidal soap, neem oil, or pyrethrin; remove by hand or with water blast

Holes chewed in emerging rosettes in spring; slime trails left overnight Ferric phosphate pellets; egg-shell or grit mulch around crowns; evening patrols
