Know before you buy
Pumice is a more durable, volcanic alternative to perlite. Unlike perlite, which can break down or float to the surface over time, pumice maintains its structure, provides additional minerals, and offers better longevity for long-term potting mixes.
This product features a consistent particle size of 3/8" x 1/4". This grade is ideal for creating air pockets in soil while still providing enough surface area to retain moisture.
Yes, this pumice is excellent for succulents and cacti. Its moderate drainage and moisture retention properties help prevent root rot while ensuring the soil doesn't stay saturated for too long.
Yes, using a layer of pumice as a top dressing or mulch can help suppress weed growth by creating a dry, inorganic barrier that prevents weed seeds from establishing contact with the soil.
BuildASoil pumice is horticultural-grade and clean, so it typically does not require rinsing. You can mix it directly into your potting medium right out of the bag.
