Hylotelephium spectabile 'Brilliant' problems — and how to fix them
Hylotelephium spectabile 'Brilliant' (Hylotelephium spectabile 'Brilliant') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Lax or flopping stems
From shade or over-rich soil. Site in full sun and lean ground; a Chelsea chop in late spring keeps the mound shorter and self-supporting.
Root and crown rot
The chief killer, caused by wet or compacted soil over winter. Sharpen drainage with grit and avoid waterlogging.
Slugs and snails on new growth
Emerging spring shoots are grazed in damp weather. Protect young clumps with barriers or traps early in the season.
Aphid clusters
Soft new shoots attract aphids; dislodge with a jet of water or wipe off. Usually cosmetic and easily controlled.
