Troubleshooting
Triangle Staghorn Fern problems — and how to fix them
Triangle Staghorn Fern (Platycerium stemaria) 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
Natural ageing is normal and protective; do not remove brown shield fronds as they anchor the plant.
Over-soaking / root rot
Too frequent soaking or poor mount drainage causes root and crown rot. Ensure thorough drying between waterings.
Scale insects
Check the underside of fertile fronds; treat with insecticidal soap or a cotton swab with isopropyl alcohol.
Tip browning on fertile fronds
Low humidity or infrequent watering. Soak more regularly in summer and mist the fertile fronds.
Loss of triangular frond shape
Young plants may have less pronounced lobing; adult form develops with maturity and good growing conditions.
