This is a soil additive- not soil on its own. Vermiculite is a mineral that is often added into soil in a small granule form, and it aids in the aeration and drainage of the soil. Basically, it makes sure that the roots get enough air, and that water can drain out of the soil to prevent overwatering. It also adds in many important nutrients and minerals to ensure the plant gets a full arsenal of nutrition.
Most often, people purchase vermiculite when mixing their own soils, but it can also be added into soils if you feel that your plant needs a boost. Reach out to us through phone or email to find out if vermiculite is right for you!
