What Is Vermiculite and How Is It Used?
Vermiculite is a mica-like mineral that serves as a soil amendment. It is mined out of the ground, exfoliated, and treated with extreme heat and pressure. The resulting worm-like, curly, and sterile product has the ability to expand.The silvery-gray and flaky material is so light that the small particles move when you blow on them. Vermiculite traps nutrients in the soil but it does not contain any nutrients; it has to be mixed with commercial fertilizer or compost to feed plants.
