Vasse's Staghorn Fern problems — and how to fix them
Vasse's Staghorn Fern (Platycerium vassei) 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.
Crown rot at the shield base
Caused by overwatering or poor drainage. Water must be allowed to drain completely after soaking; never allow the mounting medium to stay soggy. Remove blackened tissue if rot is detected.
Yellowing or dropping fertile fronds
Low light or acute drought stress are the primary causes. Move to a brighter position and establish a consistent soak-and-dry watering rhythm.
Scale insects on frond surfaces
Brown, waxy lumps appear on fronds or the shield. Treat by wiping affected areas with a soft cloth moistened with isopropyl alcohol. Avoid spraying soapy solutions on the felt-like trichomes of the fronds.
