Choosing the Right Sand for Carnivorous Plant Soil Mixes

Not all sand is safe for carnivorous plants. Use only silica-based sand—labeled as "play sand" or "horticultural sand" at nurseries. Avoid beach sand, construction sand, or any with lime/calcium.

Mix Ratio

1:1 silica sand to sphagnum peat moss is standard for many temperate species.

Quick Test

If vinegar fizzes on the sand, it contains carbonates—don't use it.
