About Resurrection Fern
Polypodium polypodioides · also called Little Grey Polypody, Miracle Fern · houseplant
Polypodium polypodioides is a remarkable epiphytic fern native to the Americas that can lose up to 97% of its water and fully recover when rehydrated — hence the common name Resurrection Fern. It is excellent for naturalistic displays on driftwood or cork. True ferns are generally pet-safe.
Preferred mix: Free-draining, chunky epiphytic mix or bare bark mount
Watch for — Root rot when overwatered in substrate: Avoid waterlogged conditions. The rhizomes rot if kept continuously wet. Allow slight drying between waterings.
Why resurrection fern needs this mix
Resurrection 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.
- Resurrection 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 resurrection fern struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Dense, water-holding compost rots resurrection 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 resurrection 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 resurrection fern?
Resurrection 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 resurrection 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.
Resurrection 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 resurrection fern covers the timing and technique step by step.
