Troubleshooting
Hosta 'El Nino' problems — and how to fix them
Hosta 'El Nino' (Hosta 'El Nino') 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
Though relatively slug-resistant due to thick leaves, young spring growth is still vulnerable. Apply iron phosphate pellets early in the season.
Sun bleaching
The blue-grey colour comes from a waxy bloom that is destroyed by intense sun. Site away from hot afternoon exposure to preserve the colour.
Hosta virus X
Produces mosaic-like discolouration and twisted growth. Remove and destroy infected plants; there is no cure.
Vine weevil
Root-feeding larvae cause sudden wilting. Apply nematode drenches in late summer before soil cools below 12°C.
Crown rot
Can develop in poorly drained or waterlogged conditions. Plant in beds with good structure and avoid late-autumn overwatering.
