Itea virginica 'Henry's Garnet' problems — and how to fix them
Itea virginica 'Henry's Garnet' (Itea virginica 'Henry's Garnet') 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.
Suckering spread
Forms colonies by suckers and can widen beyond its spot. Remove suckers each season, or use it for naturalising and erosion control where spread is wanted.
Muted color in shade
Too much shade dulls the signature garnet fall colour and reduces flowering. More sun yields the deepest tones.
Drought scorch
Leaf-edge browning and drop appear in sustained drought. Keep soil evenly moist and mulch, especially while establishing.
Base thinning with age
Old clumps may open up at the base. Cut the oldest stems to the ground right after flowering to renew dense growth.
