Sarah Raven Volcanic Rock Dust

Our volcanic rock dust cultivates healthier and more abundant crops and increases resistance to pests and drought. Packed with essential nutrients, this a truly natural way to add essential trace elements to your soil. This can be beneficial to apply all year round except when the ground has frozen or in windy conditions. Earthworm action will benefit the effects, as they will draw the rock dust into the soil and help release the minerals.
