Hosta 'Halcyon Blue' problems — and how to fix them
Hosta 'Halcyon Blue' (Hosta 'Halcyon Blue') 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.
Blue wax coating loss
Handling leaves, overhead watering, or strong sun strips the waxy bloom; water at the base and avoid touching the leaves unnecessarily.
Slug damage on emerging shoots
Despite good slug resistance once mature, tender spring shoots are vulnerable; apply deterrents early in the season.
Colour fading through summer
Blue colour naturally fades to grey-green by late summer; this is normal — blue colouration is best in late spring and early summer.
Hosta virus X
Watch for ink-bleed or stippled dark mottling on leaves — remove and destroy affected plants immediately.
Poor drainage in winter
In cold, wet winters the crown may rot if poorly drained; incorporate grit into heavy soils and avoid deep mulching directly over the crown.
