Staghorn Fern
Platycerium bifurcatum
Through the year 🗓️
☀️ Summer now
Soak more often in heat. A mounted staghorn can dry out in days.
🍂 Fall
Stretch soaking intervals as light fades and stop feeding by late fall.
❄️ Winter
Soak sparingly (every 2–3 weeks in cool rooms) and keep it above 55 °F.
🌱 Spring
Detach and mount any pups now, and step feeding back up as new antlers emerge.
The details
Light & placement
- Light
- Bright indirect with a little gentle morning sun; brighter than most ferns like
- Ideal PPFD
- 200–400 µmol·m⁻²·s⁻¹
- Grow-light distance
- 18–24 in below LED
Water & feed
- Watering method
- Soak the mount or root ball in a basin for 10–20 minutes, then let it drip-dry; mist the antler fronds between soaks. Water by weight: light means thirsty.
- Fertilizer
- Balanced feed at ½ strength, monthly in spring–summer; add it to the soak water.
Home & habit
- Soil
- None, ideally: mount on wood with sphagnum moss, or use pure orchid bark/sphagnum in a basket; pH 5.5–6.5
- Humidity
- High (50–70%)
- Temperature
- 60–80 °F
- Mature size
- 2–3 ft across mounted, larger with age
- Repotting
- Rarely; remount onto a bigger board as the shield fronds outgrow it
- Propagation
- Pups that form beside the shield fronds, cut away with some moss and roots; spores.
When something looks wrong
- Overwatering signs
- Black spots at the base of fronds; brown, mushy shield fronds; rot at the crown
- Underwatering signs
- Wilted, drooping antler fronds; browning tips
- Common pests
- Scale, mealybugs (check under the shield fronds)
Common problems 🩺
The usual suspects when Staghorn Fern looks unhappy. Most houseplant trouble is watering or light, not disease — see all plant problems if you are not sure which plant is the culprit.
Black or brown patches at the base
Likely cause
Overwatering — the most common way a mounted staghorn dies.
What to do
Let it dry substantially between soaks and make sure air moves freely behind the mount.
Antler fronds browning at the tips
Likely cause
Underwatering or very dry air.
What to do
Soak the mount for 10–20 minutes when it feels light, and raise humidity.
The flat shield frond turning brown
Likely cause
Completely normal. The shield browns, hardens, and becomes the plant's anchor.
What to do
Leave it alone — never peel it off. New green shields grow over the old.
