Staghorn Fern Care Guide
How to grow and care for Staghorn Fern (Platycerium bifurcatum)
The Platycerium bifurcatum, commonly known as the Staghorn Fern, is a fascinating and unique epiphytic plant native to tropical regions. Its distinct antler-like fronds make it a popular choice for indoor plant enthusiasts. Known for its resilience and unusual beauty, the Staghorn Fern thrives in indoor environments when properly cared for. This guide will walk you through all the necessary steps for maintaining a healthy Platycerium bifurcatum in your home.

Care
Light
Provide bright, indirect sunlight. Avoid direct sun, which can scorch the fronds. If natural light is insufficient, supplement with artificial grow lights.
Watering
Water thoroughly using one of two methods: soak the root ball in room-temperature water for about 5 minutes, or run water over it until saturated. Perform this process about once a week, adjusting based on your home's humidity and temperature. Allow the plant to dry slightly between waterings. Overwatering can lead to root rot, so ensure the mounting medium partially dries out before rewatering.
Humidity
Staghorn Ferns thrive in high humidity environments. Maintain humidity above 60% by using a humidifier, pebble trays, or regular misting. These epiphytes especially benefit from increased moisture in the air.
Temperature
These ferns prefer temperatures between 60°F and 80°F (15°C to 27°C). Avoid cold drafts and protect from temperatures below 50°F (10°C), which can stress or damage the plant.
Soil / Mounting Medium
Use a well-draining orchid mix or sphagnum moss mounted on a board or in a wire basket. Staghorn Ferns are epiphytes and should have their roots exposed to air circulation. While young ferns may begin in pots, they should be mounted as they mature to replicate their natural growth habit.
Maintenance
Fertilizing
Feed every two to four weeks during the growing season (spring and summer) with a balanced, water-soluble fertilizer diluted to half strength. Watch for signs of over-fertilization, such as browning frond tips or a crusty buildup on the moss or mounting medium. Suspend fertilization during the dormant season.
Pruning
Remove dead or damaged fronds with clean, sharp scissors to encourage healthy growth. Avoid trimming the basal fronds (the rounded shield fronds), even when brown and papery, as they help support and protect the plant and also absorb nutrients.
Mounting / Repotting
Staghorn Ferns rarely need repotting. Instead, remount every 2–3 years or when the plant outgrows its current mount. Signs it's time to remount include fronds extending well beyond the board, moss that dries out too quickly, or visible overcrowding of roots. When remounting, choose a larger wooden board or basket and use fresh sphagnum moss.
Propagation
Division
Propagate by gently dividing offshoots or "pups" from the parent plant. Ensure each division has its own roots and fronds before re-mounting. It's best to wait until the offshoot is at least one-third the size of the parent before separating. Handle carefully to avoid damaging the delicate root system.
Spores
Staghorn Ferns can also be propagated from spores, though this method is more complex and time-consuming. Spores can be collected from the underside of mature fronds and sown on a sterile, moist surface in a warm, humid environment. Germination can take several weeks to months and requires consistent warmth and humidity throughout the process.
Common Issues
Pests
- Cause: Dry indoor air, dusty conditions, or nearby infested plants.
- Symptoms: Presence of mealybugs or scale; white, cotton-like masses or hard, brown bumps on fronds.
- Solution: Remove pests manually with a damp cloth or cotton swab dipped in rubbing alcohol. Treat with neem oil or insecticidal soap if infestation persists.
Fungal Infections
- Cause: Excess moisture and poor airflow can lead to fungal infections.
- Symptoms: Black or brown spots on fronds, soggy base, or foul odor.
- Solution: Improve air circulation, reduce watering, and remove affected fronds. Use a fungicide if the infection spreads.
Yellowing Fronds
- Cause: Overwatering, insufficient light, or nutrient deficiency.
- Symptoms: Fronds turn yellow, wilt, or drop prematurely.
- Solution: Adjust watering schedule, move the plant to a brighter location with indirect sunlight, and feed regularly during the growing season.
With proper care, your Staghorn Fern will flourish into a dramatic, sculptural centerpiece—thriving indoors or in a shaded outdoor space. Prioritize consistent humidity, bright indirect light, appropriate watering, and secure mounting for optimal growth and long-term health.
