Orange New Zealand sedge problems — and how to fix them
Orange New Zealand sedge (Carex testacea) 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.
Loss of orange coloration
Color is most intense in full sun and cool temperatures. Plants in too much shade or in warm, humid summers will remain green rather than turning coppery-orange. Move to a sunnier spot and note that peak color display occurs naturally in autumn through winter.
Crown rot from winter wet
Prolonged waterlogging during winter is the main cause of plant death. Ensure sharp drainage, particularly in clay-based soils. Raise planting level slightly and avoid mulching against the crown. Container plants should be elevated to prevent sitting in water.
Leaf tip browning
Dry soil or wind scorch causes brown tips on the fine leaves. Water consistently during dry periods and shelter plants from cold, drying winds. Trim brown tips cleanly with scissors for a tidier appearance.
