A staghorn is an evergreen epiphytic fern (Platycerium) that grows on trees and walls instead of in the ground, with antler-shaped fronds and a shield-like base. It suits shady, humid Sydney gardens, covered patios and trees where you want a native feature plant.
This guide covers the types of staghorn, where to hang or mount one, how to water and feed it, common problems and Sydney garden costs. You will also see how to separate a staghorn fern from other plants sold as stag horn.
Key points
- Staghorn grows best in bright, filtered light with good airflow, and the fronds scorch in hot afternoon sun.
- It is mounted on a board, basket or tree, not planted in garden soil, and the base should never stay soggy.
- Mature size varies with the type (indicative — check the plant label), so choose a spot that gives it room.
- Frost damages fronds, so protect plants in colder western suburbs and the Blue Mountains.

Where to hang or plant staghorn in Sydney
- Choose a spot with bright, filtered light, such as under a high canopy, where morning sun is fine but harsh afternoon sun is not.
- Mount it on the north or east side of a mature tree in humid areas like the Northern Beaches, away from hot western walls.
- Hang baskets on a covered patio with good airflow, because stagnant air invites rot.
- Protect plants from frost in western Sydney and the Blue Mountains by moving baskets under eaves in winter.
- Keep it away from lawn mowers, whipper snippers and sprinkler spray on hard surfaces.
- Fix wall mounts into solid brick or timber, and book a licensed handyman for heavy wall fixings.
How to mount a staghorn
- Pick a solid board, hardwood slab or tree trunk that will not rot quickly.
- Fix a pad of damp sphagnum moss to the surface with a few stainless steel or plastic-coated fixings.
- Set the staghorn on the moss with its shield frond facing up, and the antler fronds free to grow.
- Tie it down with soft cord or pantyhose, without cutting into the shield frond.
- Hang the mount at eye level or above, so you can check the base easily.
- Water the base thoroughly and let it drain, then leave it undisturbed while it grips.
- Remove the ties after the roots hold firmly in the moss or on the mount.
Caring for staghorn
| Task | When | How |
|---|---|---|
| Watering | Spring to autumn, more often in heat | Soak the base, then let it dry slightly; water before 10 am or after 4 pm under the Water Wise Guidelines. |
| Feeding | Spring and summer | Use a registered seaweed tonic or fern fertiliser exactly as the label directs. |
| Misting | Hot, dry weather | Mist the antler fronds lightly, and leave the soft fuzzy coating alone. |
| Tidying | Autumn | Remove fully brown fronds with clean secateurs, but keep the shield fronds even if they turn brown. |
| Mulching and moss | Spring | Top up sphagnum moss around the base if it has shrunk. |
| Pest watch | Summer | If you see scale or white fluff, see a pest controller for advice. |
Pruning and tidying staghorn
- Remove only fronds that have fully browned, because brown shield fronds protect the roots and should stay.
- Use clean, sharp secateurs and cut close to the base without nicking the shield.
- Leave the fuzzy coating on fronds, as it is part of the plant and not a pest.
- Divide pups from the main plant only when they are big enough to survive, using a clean knife.
- Move heavy specimens with two people, and never lift a large mounted plant off a high branch yourself.
- Run any powered garden tools nearby within NSW hours: from 7 am on weekdays and Saturdays and from 8 am on Sundays and public holidays.
Common staghorn problems
| Symptom | Likely cause | Fix |
|---|---|---|
| Black or soft base | Overwatering or poor airflow | Let the base dry, improve airflow and water less often. |
| Brown, crispy frond tips | Hot sun or dry air | Move to filtered light and water the base more regularly. |
| Pale, limp fronds | Too little water or deep shade | Soak the base and move into brighter light. |
| Frost damage | Cold winter nights | Protect plants in winter and trim damaged fronds after frost. |
| White or brown bumps | Scale insects | See a pest controller before treating the plant. |
| Plant falling off its mount | Loose ties or rotten backing | Re-mount on a firm base and secure with soft ties. |

FAQ: staghorn
What is a staghorn?
A staghorn is an epiphytic fern that grows on trees and walls rather than in soil. It has flat shield fronds that cover the roots and antler-shaped fronds that carry spores. It looks best mounted on a board or hung in a basket.
Is a staghorn the same as a stag horn?
Usually yes. People spell staghorn as one word or two, and both normally mean the Platycerium fern. A few unrelated plants also share the name, such as staghorn coral and staghorn sumac, so check the botanical name before you buy.
How often should you water staghorn?
Soak the base when it feels slightly dry, more often in a hot Sydney summer and less in winter. Water before 10 am or after 4 pm to follow the Water Wise Guidelines, and let it drain so the base does not stay soggy.
Can staghorn grow outdoors in Sydney?
Yes, in a sheltered spot. Staghorn does well on shaded trees and covered patios in warm, humid suburbs. In colder western suburbs and the Blue Mountains, protect it from frost, and check the plant label for the minimum temperature of your type.
