Horticultural grade Vermiculite has become a mainstay as a component of soil-less growing mediums, as a soil amendment and in many other horticultural uses. Vermiculite has the excellent property of improving soil aeration while retaining the moisture and nutrients necessary to feed roots, cuttings and seeds for faster growth. Vermiculite possesses cation exchange properties, meaning it can hold positively-charged ions and thus retain nutrients. This mineral holds ammonium, potassium, calcium and magnesium and make them available to the growing plant. When mixed with peat, composted bark, organic compost or natural soils, vermiculite helps promote faster root growth and gives quick anchorage to young roots. These mixes help retain air, plant food, and moisture, and releases them as needed by the plant. Because vermiculite is very light and easy to handle, it easily mixes with soil, peat, composted pine bark and other composted organic materials, fertilizers, pesticides and herbicides. Gardeners also can mix it with non-soil materials for use in hydroponics. In addition to promoting growth, vermiculite can assist root anchoring and prevent mold development.
