Daylily 'Midnight Magic' problems — and how to fix them
Daylily 'Midnight Magic' (Hemerocallis 'Midnight Magic') 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.
Leaf streak
Yellow-brown leaf streaks from Aureobasidium infection; cut away affected leaves and avoid wetting foliage when watering.
Spider mites
Fine webbing and stippling on leaves during hot, dry spells; increase humidity with light misting or treat with neem oil.
Aphids
Found on tender new growth in spring; blast off with water or apply insecticidal soap. Check regularly as daylilies in active growth are attractive to aphid colonies.
Crown rot
Clumps collapse at the base in poorly drained soil; remove rotted crowns entirely, improve drainage, and replant healthy divisions.
Slug and snail feeding
Emerging spring shoots can be decimated by slugs; use iron phosphate pellets or copper tape around susceptible clumps.
