Horticultural Vermiculite provides numerous benefits by improving moisture retention and soil aeration. These properties make it ideal for seed germination, root cuttings, and soil amending.
A valuable growing medium for small area gardening and hydroponics! Vermiculite’s cation exchange properties hold and make available vital nutrients such as ammonium, potassium, calcium, and magnesium. For faster root growth and maximum yield combine vermiculite with other media such as natural soil, peat, organic compost, or bark. The mixture will hold moisture, retain air, and provide plant food with a minimal amount of water required.
Seed Germination: If used alone, add 1 tbsp. of soluble fiber per one gallon of water to the seedlings. Slower germinating seeds will require a 50/50 mix of vermiculite and peat or perlite.
Root Cuttings: A 50/50 mix of vermiculite and perlite or peat provides a prompt anchorage to the roots allowing maximum nutritional benefit. Water the vermiculite thoroughly and then insert the cuttings.
Soil Amending: Vermiculite helps lighten the soil while providing water retention. Mix 50% of volume to sandy soil. This will allow the circulation of proper air flow that is needed for optimum growth. Vermiculite may also be added to clay soil to increase drainage.
