Hosta 'Guacamole' problems — and how to fix them
Hosta 'Guacamole' (Hosta 'Guacamole') 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
Hostas are highly attractive to slugs, which shred the foliage overnight. Use iron phosphate pellets, copper tape, or encourage natural predators; avoid bare soil around crowns.
Vine weevil
Larvae feed on roots, causing sudden collapse. Apply nematodes (Steinernema kraussei) to moist soil in late summer or autumn.
Leaf scorch
Brown, papery leaf edges result from too much direct afternoon sun or drought stress. Move to a shadier position and mulch well.
Hosta virus X
Mosaic-like blotching and distortion with no cure. Destroy affected plants promptly and sterilise tools to prevent spread.
Crown rot
Caused by waterlogged soil or excessive moisture around the crown. Ensure good drainage and avoid overhead watering.
