Troubleshooting
palm sedge problems — and how to fix them
palm sedge (Carex muskingumensis) 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.
Leaf tip browning
Caused by drought stress or excessive sun exposure; ensure soil stays evenly moist and site in partial shade during the hottest part of the day.
Rust fungus (Puccinia spp.)
Orange-brown pustules appear on leaves in humid conditions; improve air circulation and remove affected foliage promptly. Fungal sprays are rarely needed if site drainage is adequate.
Clump dieback at centre
Older clumps can develop a hollow centre after several years; divide in early spring every 4–5 years to rejuvenate vigour.
