How to Mount a Staghorn Fern: A Modern Step-by-Step Guide

The Essentials for Mounting a Staghorn Fern

• A Staghorn Fern: This can be a young plant from a pot or a pup you've separated. Our Staghorn Fern Propagation guide shows you how to get a pup ready.
• A Mount: Choose a piece of untreated, rot-resistant wood like a thick wood slice, cedar plank, or cork bark. Ensure it's large enough for the fern's current size and future growth. See the Alternative Mounts section below for more options.
• Sphagnum Moss: This will be the bed for your fern's roots, holding moisture - the same medium recommended in our Staghorn Fern Watering Guide for optimal hydration.
• Securing Material: Clear fishing line, twine, or floral wire are all great options.
• Hanging Hardware & Tools: A sturdy picture hook, nails, and a hammer.
• Scissors: For cutting the moss and securing line.

Step 1: Prepare the Staghorn Fern Mount

Start by preparing your mount. Attach your hanging hardware to the back of the board, as it's much easier to do now. To create anchor points for your securing line, hammer a circle of nails partway into the front of the board, leaving them raised. This will give you a frame to wrap your line around.

Step 2: Hydrate Your Sphagnum Moss

Soak a generous handful of sphagnum moss in a bowl of water for about 10-20 minutes until it's fully saturated. Once hydrated, squeeze out the excess water. You want it damp and spongy, not dripping wet. This step is key - properly hydrated moss keeps your fern happy from day one

Step 3: Prepare the Staghorn Fern for Mounting

If your staghorn fern is in a pot, gently remove it. Carefully break away about half of the old soil from the root ball, exposing the roots. This will help them establish in the new moss. If you're mounting a pup from our propagation guide, it's already good to go.

Step 4: Create the Moss Bed on the Mount

Place a mound of your damp sphagnum moss in the center of your mount, inside the circle of nails. Shape it into a slight dome, creating a nest that is slightly larger than the fern's root ball.

Step 5: Position the Staghorn Fern on the Mount

Place the fern's root ball onto the center of the moss bed. Gently press it down. Make sure the shield frond(s) (the round, flat ones) are facing the top of the mount. Antler fronds should grow up and outwards. This orientation is important for its future growth.

Step 6: Secure the Staghorn Fern to the Board

This is the most important step!

1. Add more damp moss around and on top of the root ball, creating a secure package. Leave the shield fronds and the top growing point uncovered.
2. Take your securing line and tie a knot to one of the anchor nails.
3. Begin wrapping the line crisscross over the moss and the root ball, using the nails as anchor points. Go back and forth multiple times from different angles.
4. Pull the line taut with each pass. The goal is to create a secure "web" that holds the fern's base and the moss firmly to the board. The fern should not wobble at all.
5. Wrap around the base of the shield fronds, but never over the top of them or the central growing bud.
6. Once secure, tie off the line tightly on a nail and trim the excess.

Step 7: Final Touches - Hang Your Mounted Staghorn Fern

Trim any stray bits of the securing line. Give the moss a final light misting. Your Staghorn Fern is now mounted! Hang it in its designated spot - somewhere with bright, indirect light is ideal.

Cork Bark Slab

Cork bark is naturally rot-resistant and lightweight, making it a top choice for mounting. Its rough, textured surface gives the fern's roots plenty to grip onto as they establish. Cork also holds some moisture, which benefits the plant. The natural look is beautiful in both modern and rustic settings.

Wire Hanging Basket

A wire hanging basket lined with sphagnum moss is a great option for larger staghorn ferns or if you want a more three-dimensional display. The open wire design provides excellent air circulation around the roots and allows the fern to grow in all directions. This is especially popular for outdoor staghorn fern growing on patios and under trees.

Tree Fern Plaque

Tree fern fiber plaques are a natural, porous material that holds moisture well and provides an excellent rooting surface. They are popular with serious fern collectors and create a very natural, organic-looking mount that blends in as the fern grows.

Driftwood or Natural Branch

For a truly unique display, mount your fern on a piece of driftwood or a thick, sturdy branch. Make sure the wood is clean, dry, and free of any harmful treatments or chemicals. Driftwood pieces with interesting shapes create stunning conversation starters. If you're growing your fern outdoors, you can even mount it directly onto a living tree with rough bark.

Cedar or Cypress Plank

A rectangular cedar or cypress plank is affordable, widely available, and naturally rot-resistant. It provides a clean, modern look that works well in contemporary interiors. The flat surface makes it easy to hang with standard picture hardware.

Staghorn Fern Feels Wobbly on the Mount

You didn't wrap the line tightly or enough times. It's best to add more wrapping now to ensure the fern is completely stable. A wobbly base prevents roots from anchoring properly and is the number one cause of mounting failure.

Sphagnum Moss Dries Out Too Fast

Your moss layer might be too thin, or the location is too dry or too windy. Try adding more moss around the root ball and water more frequently. Increasing ambient humidity with a humidifier or grouping plants together can also help. See our Watering Guide for soaking techniques.

Shield Frond is Turning Brown

If it's an older shield frond at the very back, this is completely normal - they naturally turn brown and papery as new ones grow over them. Never remove healthy brown shield fronds, as they protect the roots and collect organic matter. If a new, green shield frond is browning, it could be a sign of underwatering or too much direct sun. Adjust your light conditions and watering accordingly.

Black or Mushy Spots at the Base

This is the most concerning sign. Blackening at the base of the shield fronds or around the root ball usually indicates overwatering and the beginning of root rot. The moss is staying too wet for too long. Allow the fern to dry out much more between waterings, and check that you have adequate air circulation behind and around the mount.

Mold or Fungus Growing on the Moss

A small amount of white mold on sphagnum moss is common and usually harmless, especially in humid environments. If it becomes excessive, it usually means the moss is staying too wet with too little airflow. Reduce misting frequency, improve ventilation around the mount, and consider moving it to a brighter spot. The mold should decrease as conditions improve.

Fern Is Not Producing New Growth After Mounting

Give it time - some ferns take 4-6 weeks to settle in after mounting. Make sure the environmental conditions are right: bright, indirect light, consistent moisture, and warm temperatures (60-80°F / 15-27°C). If there's still no growth after two months, check the root health - if roots are brown and mushy, the fern may have rotted. If roots look white and firm, it just needs more time and possibly a gentle feeding with diluted fertilizer.

Pests Appearing in or Around the Moss

Fungus gnats are attracted to moist organic material and may lay eggs in the sphagnum moss. Allow the surface of the moss to dry slightly between waterings to discourage them. You can also add a thin layer of fine sand or use yellow sticky traps nearby. For persistent infestations, check our Staghorn Fern main care guide's pest section for treatment options.

What is the best thing to mount a staghorn fern on?

The best mounts are untreated, rot-resistant wood like cedar, cypress, or cork bark. A tree fern plaque or a sturdy piece of driftwood also works beautifully.

What do you use to tie a staghorn fern to a board?

Clear fishing line is the most common and effective material because it's strong and becomes nearly invisible. Strips of nylon stockings, plastic-coated wire, or even zip ties can also be used. Avoid untreated copper wire, as it can be toxic to some epiphytes.

How do you prepare a staghorn fern for mounting?

If the fern is in a pot, gently remove it and shake off any loose, dense soil from the root ball. You want to expose the roots that will make contact with the sphagnum moss on the new mount.

How tight should I wrap my staghorn fern?

Wrap it firmly enough so the fern's base is snug against the moss and board, with no wobbling. However, do not wrap it so tightly that you crush the shield frond or restrict new growth. The goal is stability, not strangulation.

Can I mount a large, mature staghorn fern?

Yes, but it requires a very sturdy mount and strong hardware for hanging, as a large, water-soaked fern can be extremely heavy. The process is the same, but you will need more moss and a stronger securing material.

Can I mount a staghorn fern on a living tree?

Absolutely! Mounting on a living tree is one of the most natural display methods, especially if you grow your fern outdoors. Choose a tree with rough bark and dappled shade. Secure the fern with moss and fishing line or nylon, and it will eventually anchor itself. See our outdoor guide for more tips.

What's the difference between a wood mount and a wire basket?

A wood mount creates a flat, wall-art-style display and is great for smaller to medium ferns. A wire basket allows the fern to grow in all directions and is better suited for larger specimens or outdoor hanging. Both methods use sphagnum moss as the growing medium.
