Troubleshooting
Adagio Maiden Grass problems — and how to fix them
Adagio Maiden Grass (Miscanthus sinensis 'Adagio') 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.
Flopping in poor sun
Even this compact cultivar opens up in shade or over-rich soil; give full sun and feed lightly to keep it tight.
Self-seeding
As a Miscanthus sinensis selection it can self-sow and is invasive in some US areas; remove spent plumes before seed disperses.
Dead centre over time
Old clumps thin out in the middle; divide every 3-4 years to refresh.
Rust / leaf blight
Orange pustules or streaked leaves in damp, crowded settings; improve airflow and avoid overhead watering.
