Troubleshooting
Giant Staghorn Fern problems — and how to fix them
Giant Staghorn Fern (Platycerium superbum) 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.
Blackening, mushy crown
Crown or basal rot from overwatering and water trapped behind the shield frond. Let the mount dry properly between soaks and improve air movement.
Browning antler tips
Low humidity or dry indoor air. Raise humidity and ensure soaks fully rewet the root mass; do not strip the protective grey felt off the fronds.
Old shield frond turning brown
Normal. The sterile shield frond naturally browns and hardens with age to anchor the plant; do not remove it, as it protects the root mass.
Pale, limp fronds
Insufficient light or starvation. Move to brighter filtered light and resume feeding during the growing season.
