Troubleshooting
Muhly Grass problems — and how to fix them
Muhly Grass (Muhlenbergia capillaris) 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.
Poor flowering in shade
The signature pink plumes are sparse or absent without full sun; site in an open, bright position for the best display.
Flopping in rich or wet soil
Over-fertile or constantly moist ground produces lax, sprawling clumps; grow lean with sharp drainage to keep it upright.
Crown rot in poor drainage
Waterlogged soil, especially over winter, rots the crown; plant on free-draining ground or a slight mound in heavy soils.
Late spring green-up
Emerges late as a warm-season grass and looks dead in early spring; cut back old foliage in late winter and wait for warmth before worrying.
