Hosta 'Stained Glass' problems — and how to fix them
Hosta 'Stained Glass' (Hosta 'Stained Glass') 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 and snail damage
The large glossy leaves are highly attractive to slugs. Use iron phosphate pellets and eliminate shelter (dense mulch, leaf litter) near the crown.
Sun scorch
The glossy golden-centred leaves burn in direct afternoon sun. Ensure protection from midday heat, particularly in warmer USDA zones.
Hosta virus X
Irregular chlorotic blotches and leaf distortion. No treatment — remove and destroy infected specimens immediately.
Vine weevil larvae
Root feeding causes rapid collapse. Apply Steinernema kraussei nematodes in late summer.
Crown rot
Overly wet soils in winter promote crown rot. Ensure good drainage and avoid mulching directly against the crown in autumn.
