Hosta 'Fire Island' problems — and how to fix them
Hosta 'Fire Island' (Hosta 'Fire Island') 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 golden-yellow leaves are a prime target. Use iron phosphate pellets, rough mulch barriers, and nightly hand-picking during wet weather.
Leaf scorch
Too much afternoon sun causes brown patches on the golden leaf surface. Reposition or provide shade from midday onward.
Colour loss in deep shade
Golden-leafed hostas require some light to produce the pigment; in full shade leaves revert to pale green. Add filtered light if colour is poor.
Vine weevil
Root damage causes wilting and plant collapse. Apply nematode biological control in late summer.
Hosta virus X
Produces mottling and distorted growth. Remove and destroy infected plants promptly.
