About Pyrrosia piloselloides
Pyrrosia piloselloides · also called Dwarf Felt Fern, Running Felt Fern · houseplant
Pyrrosia piloselloides is a tiny creeping epiphytic fern from tropical Asia, forming chains of small, round to oval, fleshy fronds along a wiry running rhizome. Often grown mounted on bark, it carpets surfaces like a living bead curtain. Drought-resistant and undemanding, it suits terrariums, mounts and bright, warm, humid interiors.
Preferred mix: Epiphytic — mount or very open mix
Watch for — Rot from constant wetness: A waterlogged mount or soggy mix rots the thin rhizome. Ensure airflow and let surfaces approach dryness between waterings.
Why pyrrosia piloselloides needs this mix
Pyrrosia piloselloides is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Pyrrosia piloselloides is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons pyrrosia piloselloides struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates pyrrosia piloselloides's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for pyrrosia piloselloides.
pH — does it matter for pyrrosia piloselloides?
Pyrrosia piloselloides is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
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 decent bagged houseplant compost works for pyrrosia piloselloides as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Drainage and the pot
A pot with a drainage hole and a saucer you empty after watering is all pyrrosia piloselloides needs — the free-draining mix does the rest.
Refresh pyrrosia piloselloides's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for pyrrosia piloselloides covers the timing and technique step by step.
