Troubleshooting
Daylily 'Fragrant Returns' problems — and how to fix them
Daylily 'Fragrant Returns' (Hemerocallis 'Fragrant Returns') 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.
Rebloom failure
Most common when the clump is overcrowded, under-fertilised, or in insufficient light. Divide every 3 years, feed after first bloom, and ensure full sun.
Fragrance reduction
Older or congested clumps produce less scent. Regular division and good fertility maintenance restore fragrance intensity.
Thrips
Silvery streaking on yellow petals caused by thrip feeding. Apply spinosad in early morning; severe infestations reduce flower quality across rebloom cycles.
Rust
Puccinia hemerocallidis can cycle through multiple infections across the long growing season of a rebloomer. Monitor leaves regularly and remove infected tissue promptly.
Slug and snail damage
Both early-season foliage and late-season rebloom scapes are vulnerable. Use iron phosphate bait or manual removal; check under mulch.
