Troubleshooting
Daylily 'Chorus Line' problems — and how to fix them
Daylily 'Chorus Line' (Hemerocallis 'Chorus Line') 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.
Reduced rebloom
Rebloom requires adequate fertiliser, consistent moisture, and regular deadheading. Clumps that are too congested will rebloom poorly — divide every 2-3 years.
Petal spotting
Water droplets on petals during overhead irrigation or rain cause spotting on the pale pink blooms. Water at the base and in the morning to minimise this cosmetic issue.
Gall midge
Contarinia quinquenotata larvae cause swollen, unfilled buds. Remove and destroy all affected buds as soon as observed; there are no effective registered chemical treatments.
Aphids
Colonies appear on scapes and buds in spring. Manage with insecticidal soap or water jets; populations usually decline as natural enemies establish.
Daylily rust
Yellow-orange spores on leaves. Remove affected foliage and apply appropriate fungicide if spread is significant.
