The granules help retain moisture and nutrients in the growing mix, making this a useful ingredient for plants that benefit from more consistent moisture. Vermiculite also helps improve soil aeration and drainage, supporting oxygen movement through the soil and helping reduce waterlogging. It works as a soil ingredient rather than a complete growing medium, so mix it into the soil or growing materials suited to your planting project.

Usage tips

It can also be used in seed-starting blends with materials such as coco coir, bark, mulch, or vermicompost. For starting seeds, incorporate it into the starter medium to help maintain moisture around developing seedlings. The product is also suitable for herb gardens, flowers, vegetables, greenhouses, and tropical gardens.
