Pumice Sand Fine Grain Horticultural Media - Bonsai Succulent Plant Alpine Soil

Pumice Sand Fine Grain Horticultural Media - Bonsai Succulent Plant Alpine Soil

We go to great lengths to bring you this special fine sand grain graded volcanic horticultural pumice. Pumice is used in all the best bonsai growing soil mixes. Used as a proportion of any soil mix this product will help to increase the strength and vitality of all plants.

This product is the fine 'Sand' grade of pumice. Traditional horticultural sand or the coarser Japanese river sand almost entirely consists of fine flint particles. Whilst these may in some circumstances promote drainage they add a lot of weight and bring nothing in relation to bioactivity to a mix. Pumice sand brings great benefit to fine particle soil mixes used in bonsai and specialist horticulture.

100% frost proof, lasts indefinitely and can be re-used over and over. Fine particle promotes drainage whilst allowing moisture into the particle for gradual release to plant roots even in relitively small pots.

1-3mm mesh graded to produce an approximate particle size close to this range.

pH typically in the range 7-8.

This product has a higher weight compared with our coaser grades because the fine particles represent greater density for a given volume.

Pumice is a naturally occuring product. The colour of this material will vary depending upon the deposits being mined and also the moisture content. Pictures are for illustration and represent what the product typically looks like.

A FANTASTIC PRODUCT FOR GROWING CACTI, ALPINES AND CITRUS.

Using Kaizen Bonsai Pumice & Lapillo
Our Pumice and Lapillo products are horticultural grade materials. Their use is a little different from other similar products you may have encountered, especially pumice where less absorbent hard grade (intended as industrial abrasive) materials are most commonly encountered. In general we would recommend mixing these products with other ingredients with desirable characteristics, for example Bark or Moler. For more information see our Guide to Selecting Bonsai Soils.

1-3mm particle size which means all of the particles will pass through a 3mm screen so some pieces will be oversize in length. 

When you receive your Pumice or Lapillo you will notice the material contains some degree of fines or dust. This is as a result of abrasive action during processing, packaging and transit. Being slightly damp this will bind to the particles. A light shake through a sieve will remove the loose fine particles.  Do not sieve excessively but simply mix and or pot up your plants in the normal way. Once complete water thoroughly, watching the water that drains from the bottom of the pot, once this runs clear you are finished. The finer dust will simply wash away leaving a very high percentage of clean micro-pores that will be colonised by fine feeder roots and mycelium resulting in the perfect natural rhizosphere and will ensure your plants absolutely flourish.

Any dust contained within our crushed aggregate products will settle into the spaces between larger particles and once removed will not significantly effect the volume you purchased.
