Daylily 'Sanctuary' (Hemerocallis 'Sanctuary') 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.
Petal spotting on large blooms
Ruffled flowers trap water droplets, causing unsightly brown spots; always water at the base and deadhead spent blooms promptly.
Leaf streak
Tan-brown streaking on foliage due to fungal infection; cut away affected leaves and thin clumps for better airflow.
Aphids
Colonise tender new growth and scapes; treat with insecticidal soap or introduce natural predators such as lacewings.
Rust
Orange spore pustules on leaf undersides in warm, humid summers; remove infected foliage and apply fungicide if severe.
Hemerocallis gall midge
Swollen, non-opening buds contain white larvae; remove all affected buds immediately and dispose of them away from the garden to interrupt the pest cycle.
