Platycerium superbum is a epiphyte naturally occurring in and near rainforests but is now also widely cultivated as an ornamental plant for gardens.
In both naturally occurring and propagated forms, these ferns develop a humus-collecting "nest" of non-fertile fronds and in doing so can grow up to 1 metre wide. The ferns also develop hanging fertile fronds that can reach up to 2 metres long.
Both fertile and non-fertile fronds are broad and branching and grown to resemble the horns of a stag or elk, thus the common names stag horn or elk horn.
The plant gives off many tiny spores that drift to nearby trees to reproduce.
Here’s a clear, practical bullet-point care guide for Platycerium (Staghorn Fern) in mounted housing:
🌿 Platycerium (Staghorn Fern) Care – Mounted
Light
-
Bright indirect light is ideal
-
Can tolerate gentle morning sun (1–2 hours)
-
Avoid harsh midday or afternoon sun (causes leaf burn)
-
Indoors: near east- or north-facing window
Watering (Mounted Plants)
-
Soak the entire mount in water for 10–20 minutes
-
Frequency:
-
Let excess water drain completely
-
Shield fronds should dry slightly between waterings (not bone dry)
Humidity
-
Prefers 60–80% humidity
-
Ideal for bathrooms, balconies, or near humidifiers
-
Mist lightly in dry climates (avoid constant wet fronds)
-
Good air circulation is essential to prevent rot
Temperature
-
Best range: 18–30°C (65–86°F)
-
Avoid temperatures below 10°C (50°F)
-
Protect from cold drafts and heaters
Fertilizing
-
Use balanced fertilizer NPK 19–19–19
-
Mix ½ teaspoon in 1 liter of water
-
Apply:
-
Apply by soaking or pouring gently over roots/shield fronds
-
Flush with plain water once a month to prevent salt buildup
Mounting Medium
-
Use sphagnum moss, coco fiber, or tree fern fiber
-
Keep medium airy, not compacted
-
Replace moss if it breaks down or stays soggy
Pruning & Maintenance
-
Do not remove brown shield fronds (they protect roots)
-
Trim only damaged or dead antler fronds
-
Avoid wiping fronds (they have protective fuzz)
