Horticultural Vermiculite - Medium Grade (3mm-5mm) - 10 Litres

Horticultural 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 is permanent, clean, odourless, nontoxic and sterile. It will not deteriorate, turn mouldy or rot.The pH of vermiculite is essentially neutral (7.0-9.5) but owing to the presence of associated carbonate compounds, reactions are normally in the alkaline direction. Vermiculite possesses cation exchange properties, thus it can hold and make available to the growing plant ammonium, potassium, calcium and magnesium. When mixed with peat, composted bark, organic compost, or natural soils, vermiculite like perlite 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 and fertilizers.
