About Pilea nummulariifolia
Pilea nummulariifolia · also called creeping charlie, Swedish ivy pilea · houseplant
Pilea nummulariifolia is a fast trailing Caribbean groundcover with round, quilted, coin-shaped leaves on wiry red-tinged stems. It spills from hanging baskets or carpets terrarium floors, rooting where nodes touch moist soil. Loving warmth, humidity and bright indirect light, it is an easy, pet-safe trailer that resents drying out fully or cold draughts.
Preferred mix: Light, peat-free, well-draining houseplant mix
Watch for — Crispy brown leaf edges: Almost always low humidity or the soil drying out completely. Raise humidity and keep the mix evenly moist.
Why pilea nummulariifolia needs this mix
Pilea nummulariifolia is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Pilea nummulariifolia 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 pilea nummulariifolia 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 pilea nummulariifolia'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 pilea nummulariifolia.
pH — does it matter for pilea nummulariifolia?
Pilea nummulariifolia 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.
