- Increase water and nutrient retention : Vermiculite soaks up water like a sponge. It holds that water until the soil starts to dry out then releases it. This is good for moisture loving plants but not so good for plants that like dryer soil. Vermiculite naturally reacts with soil compounds and makes available other nutrients such as calcium, potassium and magnesium.
- Aerates the soil, resulting in healthier, more robust plants
