Troubleshooting
Zebra Grass problems — and how to fix them
Zebra Grass (Miscanthus sinensis 'Zebrinus') 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.
Loss of horizontal banding
The creamy bands are temperature-induced, not light-induced. They are most vivid in late summer and can be faint in early season or in cool, overcast conditions — this is normal. Insufficient sun causes overall pallor; move to a sunnier position.
Crown rot in winter
Persistent waterlogging around the crown leads to rot and plant loss. Improve drainage before planting and avoid mulching directly over the crown in areas with wet winters.
Rust (Puccinia miscanthi)
Orange-brown pustules on leaf undersides, typically in late summer. Remove infected leaves. Maintaining plant vigour and avoiding overhead watering reduces severity. Rarely fatal to established clumps.
