Vermiculite Premium Grade 12 Qt. Bag
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.
