Wallich's Staghorn Fern problems — and how to fix them
Wallich's Staghorn Fern (Platycerium wallichii) 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.
Brown shield fronds turning black
Natural aging of shield fronds is normal — do not remove them. Black rot spreading from the crown indicates overwatering or prolonged wetness at the base. Allow the mount to dry out fully between waterings.
Pale or bleached fertile fronds
Caused by excessive direct sun exposure. Move the plant to bright but filtered light. Some whitish coating on fronds (stellate trichomes) is natural and should not be wiped off.
Slow growth or stunted pups
Usually a result of insufficient humidity, low light, or lack of nutrients. Increase ambient humidity, move to a brighter spot, and resume monthly fertilising during the growing season.
