Does pumice absorb water?
It is basically whipped volcanic glass that is made up of tiny air bubbles. This means that pumice is a lightweight volcanic rock that makes it perfect for use as a soil amendment. … It reduces water runoff and fertilization by increasing soil absorption in sandy soils. It also absorbs excess moisture so roots don’t rot.
Is pumice good for soil?
