Pumice 7mm – 20mm 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.

Pumice 7mm – 20mm is ideal for bonsai, cactus, succulent and no till gardening enthusiasts for its amazing drainage.

Pumice is a light siliceous vesicular volcanic rock that is suitable for use in horticulture and hydroponics. Its porosity provides air spaces that maintain aerobic conditions around the roots while water is contained within the pores. Surface tension around the outside of the pumice particles increases water-holding capacity of the growing medium.

Our pumice 7mm – 20mm is mined from a land based resource, within 50kms of Lake Taupo in the North Island of New Zealand, and it is characterized by its relative hardness and light weight in comparison to competing aggregates. The washing and screening of our pumice particularly for horticultural applications means that no “fine” particles are included. Unwashed pumice can cause “concreting” and higher water holding capacity than required, consequently effecting root development.

This hardness and porosity allows free drainage lowering the risk of root-rot diseases.
