Lindheimer's Muhly problems — and how to fix them
Lindheimer's Muhly (Muhlenbergia lindheimeri) 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.
Large mature size
Reaches up to 1.5 m tall and wide and can crowd small beds; give it generous spacing and use it where its bold scale fits.
Flopping in shade
Loses its upright fountain form and sprawls in too little light; full sun is essential for a dense, well-shaped clump.
Winter dieback in colder zones
Less reliably evergreen near the edge of its hardiness; cut back tattered foliage in late winter to refresh the clump.
Crown rot in wet soil
Constantly wet or poorly drained ground rots the crown; ensure sharp drainage, especially over winter.
