Hosta 'Halcyon' problems — and how to fix them
Hosta 'Halcyon' (Hosta 'Halcyon') 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.
Slug damage
Young emerging leaves are the most vulnerable; apply slug nematodes or copper deterrents in early spring before leaves fully unfurl.
Leaf bleaching
Blue colour fades to green or yellow-green from too much direct sunlight; relocate to a shadier position.
Hosta virus X (HVX)
Ink-bleed mosaic patterns in the leaf tissue; no treatment — dig up and dispose of plants well away from the compost heap.
Crown rot
Usually caused by poor drainage or mulch piled against the crown; improve drainage and clear mulch from the plant base.
Deer and rabbit browsing
Young shoots are highly palatable to deer and rabbits in rural gardens; fencing or repellent sprays offer the most reliable protection.
