ABOUT PUMICE
It resembles a sponge because it consists of a network of gas bubbles frozen amidst fragile volcanic glass and minerals. All types of magma (basalt, andesite, dacite, and rhyolite) will form pumice. During an explosive eruption, volcanic gases dissolved in the liquid portion of magma expand rapidly to create a foam or froth; in the case of pumice, the liquid part of the froth quickly solidifies to glass around the glass bubbles.

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 is mined from a land based resource, within 50kms of Lake Taupo, the original source of the aggregate. As a result our pumice is characterized by its relative hardness and lightweight 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.

WHY PUMICE?
Permanent, Weathered, Strong, Highly Porous, Inert, Long Life Growing Media, extensively used in commercial Horticulture for a range of applications.  pH 6.9  (near neutral out of the bag) Non-toxic and naturally proven by nature as perfect for fresh water fish growth, abundant in volcanic regions like NZ, proliferating with Trout and aquatic life, swimming in Pumice lined streams. Pumice is clean ready to use, out of the bag.  Abundant high quality, local regional sources. 500 m2/litre of surface area for optimised bacterial colonisation to enhance organic breakdown, just as nature intended. Pumice per unit volume is inexpensive, sufficiently so, to be continuing to gain market share in the commercial horticultural sector, bonzai, orchids, fruit trees and numerous other specialist applications.

GROWING SUCCULENTS

Pumice is another ideal growing medium for cacti and succulents. The hardness and porosity allows for drainage, lowering the risk of root diseases The soil beneath the mulch stays moist longer and is less likely to compact from watering.
