Vermiculite is a soil additive that uses its accordion-like particles
to amend soil by retaining water, improving aeration and prolonging
nutrient release. Its ability to retain both air and water makes
vermiculite ideal for conditioning container soils. Vermiculite can also
be used for seed germination, bulb storage and flower arranging. OMRI®
