Soil for Schlumbergera

Use an airy, free-draining mix that holds some moisture for Christmas cactus. RHS lists cactus compost or peat-free John Innes No. 2 with leaf mold and grit, not dense garden soil.

Best soil mix

RHS lists standard cactus compost or a peat-free John Innes No. 2 mix with leaf mold and grit for Christmas cactus. The aim is a lighter, more open medium than dense, moisture-retaining garden soil. Neither recipe is mandatory for every hybrid.

The container should drain freely while the medium holds some moisture. A mix that stays wet in low light raises the risk of disease and root problems, so the pot must not stand in drained water.

Separate indoor and outdoor advice

Match the mix to the pot and setting

This medium guidance is for potted Schlumbergera kept as an indoor holiday cactus. The group is a rainforest or epiphytic cactus context, not evidence for a garden-bed desert-cactus mix or a year-round exposed outdoor pot.
