Pumice
Best soil amendment for gardeners seeking superior drainage and root health.
Ditch the perlite for this volcanic rock if you want a more durable, mineral-rich foundation for your living soil. It is heavier and less convenient to handle than lighter alternatives, but the superior aeration and long-term structural integrity make it the clear choice for serious growers.
