DIY Sarracenia Soil Mix: Peat, Sand, Perlite, and Vermiculite Options

A grower asks for proportions to mix their own Sarracenia soil and if vermiculite can replace perlite.

Standard Mix

By volume: 50% sphagnum peat moss (fluffed), 30% silica sand, 20% perlite. Silica sand = quartz grains (mined or artificial). Avoid river/beach sand. Find at sandblasting suppliers, pool stores.

Vermiculite Substitution

Some warn against vermiculite (compacts over time). If used, add silica sand, orchid bark, chopped styrofoam, or plastic BBs to maintain aeration and drainage.
