Blue Hosta 'Halcyon' problems — and how to fix them
Blue 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.
Loss of blue colour
The blue is a removable wax bloom; too much sun, heat or overhead watering rubs it off, leaving green leaves. Keep in shade and water at the base.
Slugs and snails
Chew holes in the smooth leaves, especially soft spring growth. Use iron-phosphate pellets, traps or copper barriers.
Crown and root rot
Cold, waterlogged soil rots the crown. Plant in free-draining soil and avoid burying the crown too deep.
Hosta Virus X (HVX)
Incurable virus causing mottling and tissue distortion. Buy from reputable, clean sources and destroy any infected plants.
