Hosta 'Sum and Substance' problems — and how to fix them
Hosta 'Sum and Substance' (Hosta 'Sum and Substance') 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 leaves are prime targets; use copper barriers, beer traps, or nematodes (Phasmarhabditis hermaphrodita) in spring before damage builds up.
Hosta virus X (HVX)
Mosaic patterns or 'ink bleed' marks on leaves with no cure; remove and dispose of affected plants away from the garden.
Leaf scorch
Brown crispy patches from too much direct sun or drought; relocate to deeper shade and maintain even moisture.
Crown rot
Soft, malodorous crown from overwatering or poor drainage; improve drainage and avoid mulching directly against the crown.
Vine weevil
Wilting despite adequate moisture may indicate root damage by vine weevil larvae; apply nematodes in late summer.
