Hosta 'Midnight Rider' problems — and how to fix them
Hosta 'Midnight Rider' (Hosta 'Midnight Rider') 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
Small-leaved hostas are as vulnerable as large ones. Surround containers with copper tape and apply slug-deterrent grit or pellets around in-ground plants.
Leaf scorch
Thin, dark leaves can scorch even from morning sun in summer. Move to a shadier position if bleached patches appear.
Root constriction in containers
Compact growth can lead to pot-bound conditions within 2-3 years. Repot in early spring into a container one size larger.
Crown rot
Standing water in containers or poorly draining beds causes crown rot. Ensure drainage holes are clear and use free-draining compost.
Vine weevil (container)
Container plants are especially susceptible to vine weevil grubs. Apply nematodes to container compost in late summer and consider using a neonicotinoid-free systemic drench where permitted.
