Troubleshooting
Red Rooster Sedge problems — and how to fix them
Red Rooster Sedge (Carex buchananii 'Red Rooster') 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.
Mistaken for dead
Its coppery-bronze colour is natural, not a dying plant. Healthy blades are firm and upright; only dry, brittle leaves are truly dead.
Browning, crisping foliage
Drought or heat stress. Keep soil consistently moist, particularly in containers and hot sites.
Floppy, loose habit
Too much shade or over-feeding. Grow in full sun and reduce fertiliser for a tight, upright clump.
Crown rot in winter
Waterlogged, heavy soil. Improve drainage and avoid cold, wet conditions over winter.
