Pumice is an all nature soil aerator that enhances drainage in raised beds and pots.
Consisting of microscopic pores on the outer surface, pumice releases water at a steady rate whilst retaining nutrients and releasing them back slowly to the soil. Pumice can also be soaked in nutrient solutions for 24hrs prior to mixing with soil.
Ideal for bonsai, cactus, succulent and no till gardening enthusiasts for its amazing drainage abilities.
This is the lightest grade of pumice and cheapest option for shipping.
