Daylily 'Mozhart' (Hemerocallis 'Mozhart') 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.
Bud blast

Aphids
Infest scapes and flower buds in spring; treat with insecticidal soap or introduce beneficial insects such as parasitic wasps.
Leaf streak
Fungal disease causing tan or brown streaks; improve airflow and remove affected leaves promptly.
Crown rot
Wet or poorly drained soil causes crown collapse; improve drainage and replant healthy sections in well-amended soil.
