Troubleshooting
Bamboo Muhly problems — and how to fix them
Bamboo Muhly (Muhlenbergia dumosa) 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.
Frost damage to canes
Hard freezes below −7°C can damage or kill canes to the ground. Cut dead canes back in late winter; the plant typically resprouts vigorously from the root crown in spring if roots are alive.
Overwatering / root rot
In dense, poorly drained, or amended soils, overwatering causes yellowing, wilting, and root rot. Ensure very sharp drainage; err strongly on the side of underwatering once established.
Wind topple in exposed sites
Tall canes in very exposed, windy sites may lean or lodge after storms. Site in a location with some wind protection, or cut back canes by one-third in early spring to maintain a lower, sturdier profile.
