Daylily 'Bumble Bee' problems — and how to fix them
Daylily 'Bumble Bee' (Hemerocallis 'Bumble Bee') 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.
Fading eye colour
In very hot climates the dark eye zone can fade in midday heat. Plant where afternoon shade softens the most intense sun, or choose a cooler exposure.
Thrips
Cause silvery streaking and distortion in the eye zone on petals. Monitor buds; apply spinosad-based spray when thrips are detected.
Aphids
Common on emerging scapes in spring. Spray with insecticidal soap or dislodge with water; avoid systemic insecticides during peak pollinator activity.
Root rot
In poorly draining or compacted soils the crown may rot. Improve drainage before planting and avoid mulching directly against the crown.
Leaf streak
Fungal streaking causes yellow-brown banding on foliage. Cut back affected leaves, improve spacing, and avoid overhead watering.
