Description
Coarse Pumice is a fantastic aggregate amendment for potting substrates. it is a volcanic rock biproduct which has expanded in extremely high heat, then ground down into chunky sized rocks. It’s much denser than perlite, so if used in a chunky, airy mix it won’t slowly float to the top of the pot with each watering!
It’s porous nature means water containing minerals and nutrients can travel their way into areas of the pot that are drier and not compromise the fantastic air flow. Coarse Pumice is absolutely perfect for plants with chunky, THICK roots, they will wrap themselves comfortably around the Pumice’s high surface area.
