Troubleshooting
Zebrinus Zebra Grass problems — and how to fix them
Zebrinus 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.
Flopping habit
'Zebrinus' is naturally prone to splaying after rain or in shade; site in full sun, keep feeding lean, or use a discreet ring support.
Faded banding
The gold zebra stripes weaken in shade and early in cool seasons; full sun and summer warmth are needed to develop and hold the markings.
Self-seeding / invasiveness
Can self-sow and is invasive in parts of the US; cut off spent plumes before seed sets.
Hollow centre with age
Mature clumps die out in the middle; lift and divide every few years to keep them vigorous.
