Hillii Staghorn Fern problems — and how to fix them
Hillii Staghorn Fern (Platycerium hillii) 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.
Blackened, mushy frond bases (overwatering)
Too-frequent watering or a mount that stays wet causes rot. Let it dry between soaks and ensure the mount drains and dries freely.
Wilting, browning antler fronds (underwatering)
Limp, drooping antlers signal the mount went bone dry too long. Soak thoroughly and settle into a regular soak-and-dry rhythm.
Browning shield fronds
The flat sterile shields naturally brown with age and should be left in place; do not pull them off, as they protect and feed the roots.
Scale insects
Brown bumps on fronds, sometimes mistaken for spores. True spores form in defined patches on antler tips; scattered raised bumps are pests, treated with neem or horticultural oil.
