Wonder Soil®

Wonder Soil is a highly compressed planting medium that expands about ten times its original size when you add water. It contains a water-retaining polymer that expands to absorb water, slowly releasing it as the soil dries, improving survival rates of transplants. The amount of potting soil contained in this compressed brick is deceiving. In fact, once hydrated, the brick expands to over 2 gallons.

Made from sterile coir, it is nutrient-free (we recommend using it with a complete water-soluble fertilizer). Not for use with food plants, it can be used alone or mixed into potting soil to improve retention of water and nutrients.
