Which compost pilea peperomioides 'sugar' needs
For pilea peperomioides 'sugar' the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. A peat-free houseplant mix with added perlite and a little bark drains fast and prevents soggy roots. Slightly acidic to neutral pH suits it. The variegated form is a touch slower and benefits from a particularly airy, free-draining medium.In British garden centres the bagged growing medium is sold simply as “compost” (multipurpose, ericaceous, or loam-based John Innes), which is a different thing from the rotted garden “compost” you make in a heap — for a pot you want the bagged kind.

A good peat-free multipurpose grows pilea peperomioides 'sugar' perfectly well; the one habit to change is watering — peat-free dries faster at the surface while still moist below, so check by feel a knuckle deep rather than trusting the look of the top.
