Description
Vermiculite is a natural mineral that expands when heated, creating a lightweight, absorbent growing medium ideal for horticultural use. It is commonly used to improve soil structure while increasing moisture and nutrient retention around plant roots.
When added to soil or potting mixes, vermiculite helps maintain consistent moisture levels, making it especially useful for seed germination, young plants, and moisture-loving species. It also improves aeration while holding essential nutrients that plants can access over time.
Vermiculite is sterile, pH-neutral, and does not break down, making it a reliable and long-lasting soil amendment for home gardeners and professional growers alike.
