How to care for Staghorn Fern
Platycerium bifurcatum · Polypodiaceae
The staghorn fern is an epiphyte that grows on trees in the wild, producing antler-like fertile fronds and flat shield fronds that hug its mount. Indoors it is most often grown mounted on a board or in a hanging basket rather than a standard pot. Its sculptural form makes it a living wall ornament as much as a houseplant. Water roughly every 7 days while it's growing (about every 12 in winter), give it bright, indirect light, kept above 50°F (10°C) — it wants humid air.
Care at a glance
Soak the root ball or mount in water for 10–20 minutes, then let it drip dry; let the medium approach dryness between soaks.
Bright, filtered light near an east or shaded south window; it tolerates a little gentle morning sun.
Balanced liquid feed at half strength monthly in the soak water during spring and summer.
Mistakes that kill this plant
- Peeling off the browning shield fronds thinking they are dead leaves.
- Keeping the mount constantly wet in winter.
- Wiping the fuzzy coating off the fronds — it protects them from sun and water loss.
Seasonal tips
- Water noticeably less in winter — cool, wet sphagnum is how most mounted staghorns die.
- Never remove the brown shield fronds; they are meant to turn papery and protect the root ball.
- Summer outdoors in bright shade gives vigorous growth — bring it in well before nights cool.
