Needle Grass problems — and how to fix them
Needle Grass (Stipa capillata) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot in wet or clay soils
The primary cause of failure with Stipa capillata. Wet, poorly drained soil, especially in winter, rapidly kills the crown. Plant in raised beds, gravel gardens, or add at least 30% grit to the planting hole.
Awn entanglement in pet fur
The needle-sharp, barbed awns readily attach to and penetrate animal fur, skin, and mucous membranes. If grown in pet-accessible gardens, cut down the fruiting stems before seeds fully mature to reduce the hazard.
