About Bear Paw Fern
Aglaomorpha meyeniana · also called Bear's Paw Fern, Meyen's Drynaria · tropical
Aglaomorpha meyeniana is a spectacular epiphytic fern from the Philippines, with deeply lobed fronds resembling a bear's paw. Its thick, creeping rhizomes are covered in golden-brown scales and anchor it to trees or bark mounts. True ferns are broadly pet-safe, and this species has no documented toxicity.
Preferred mix: Chunky, free-draining epiphytic mix or bark mount
Watch for — Rotting rhizomes: Occurs when the thick rhizomes are kept continuously wet or buried in soggy substrate. Ensure excellent drainage; the rhizomes should rest on, not be buried in, the growing medium.
Why bear paw fern needs this mix
Bear Paw Fern drinks mostly through its central cup, not its roots — so it wants a light, open, fast-draining bark mix and only a shallow pot.
- Bear Paw Fern is an epiphyte: its small root system mainly clings on, while the rosette "tank" does the drinking — so the mix only needs to anchor it and breathe.
- An open bark mix lets the few roots get air and dries fast, mimicking the tree-fork or rock crevice it grows in naturally.
- Because the cup feeds it, a soggy root zone gives no benefit and only invites base rot.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons bear paw fern struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Dense, water-holding compost rots bear paw fern at the base where the leaves meet the soil — the rosette can look fine while the crown is already failing.
- A deep pot full of mix stays wet in the middle long after the surface dries; bromeliad roots are too shallow to ever use it.
- Garden topsoil compacts and starves the few roots of air.
Potting bear paw fern deep in ordinary compost as if the roots do the feeding. Use a shallow pot of open bark mix and keep the soil only barely moist.
pH — does it matter for bear paw fern?
Bear Paw Fern likes a slightly acidic mix (around pH 5.0-6.0), which a bark-based blend gives naturally. Cup-water quality matters more than soil pH — use rain or filtered water.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A bagged epiphytic or orchid mix works well for bear paw fern with a little extra perlite. The DIY ratio above is easy and cheap if you already keep orchids.
Drainage and the pot
A shallow, well-drained pot is ideal — the rootball should never sit in water. Keep the central cup topped up instead; that is how the plant actually drinks.
Bear Paw Fern rarely needs repotting — it flowers once then produces pups. Move pups to fresh bark mix; bark breakdown is slow enough that the parent rarely needs it. When the time comes, our repotting guide for bear paw fern covers the timing and technique step by step.

What is the best soil mix for bear paw fern?
2 parts orchid bark or coarse epiphytic mix : 1 part perlite : 1 part peat-free compost. Bear Paw Fern is an epiphyte: its small root system mainly clings on, while the rosette "tank" does the drinking — so the mix only needs to anchor it and breathe.
Can I use normal potting soil for bear paw fern?
