Previous customers: Please note the genuine Japanese pumice (Hyuga) now being imported is slightly different in appearance and is of a superior quality compared to conventional pumice (previous stock). Please read the updated product description below. Please note that 3 different sizes of this product is stocked;   Fine (1-3mm),   Small (3-6mm)   and   Medium (5-8mm). What is it? Japanese pumice, or Hyuga as it is known in Japan is a naturally occurring volcanic product from the south part of Miyazaki Prefecture in Japan. Hyuga vs Pumice These two products are very similar in characteristics however due to the manner in which this Hyuga is formed in nature it is slightly softer and more porous than conventional pumice. In fact Hyuga is so porous it will sink, which reduces erosion when watering.  Due to the porosity of Hyuga aggregates in your growing mixes it enhances: water retention nutrients oxygen It is suitable for a wide range of plant species as it has an essentially neutral pH of 6. How to use? Japanese pumice is recommended for Rhododendron (including Azalea), general pot plants, orchids and it of course forms a crucial part of many bonsai growing mixes. If I had only one soil component to use for bonsai it would be 100% pumice. If you have akadama, add some. - Michael Hagedorn As Hyuga will not under normal circumstances break down it can be sifted and re-used however if you intend doing so a disinfecting treatment using Sporekill is strongly recommended to reduce the risk of spreading fungal or bacterial issues. Hyuga can be combined with other elements such as akadama or peat (no more than 20% of the total mix). Due to the good drainage qualities of hyuga it is very often used to assist a sick tree to regain vigor and health. In such a case 100% Japanese pumice may be used. Here are a few recipes from leading international bonsai practitioners: Michael Hagedorn 80% pumice and 20% composted pine bark for strong roots and early tree development. Pumice provides the widest range of healthy growing conditions. You can over water it, under-water it, and it creates great fine root growth second only to pumice mixed with about 50% akadama.  Boon Manakitivipart 1 part pumice, 1 part lava, 1 part akadama, 1 handful decomposed granite and 1 handful horticultural charcoal. Bjorn Bjorholm Akadama, lava rock, and pumice. Use a 1:1:1 ratio respectively for conifers and a 2:1:1 ratio respectively for deciduous and broadleaf evergreen species.

Features Particle size = 1 ~ 5mm Growing medium of Japanese bonsai masters High quality Ibaraki brand akadama Hard type (retains shape longest) Exclusively imported from Japan by Bonsai Tree. Available in 2L bag, 5L bag and 14L bags. Description Akadama is a granular volcanic clay-like (although it is not clay) mineral which occurs naturally in Japan. It has been extensively used by Japanese gardeners and bonsai artists for many centuries as a growing medium for bonsai trees and other container-grown plants. It is mined from the surface of the ground, after which it is graded and packaged. Unlike   LECA   it is not fired at high temperatures however when it is mined from greater depths it tends to be harder or it might be slightly baked. It has many unique qualities, one of which is that when it is wet it has a darker colour so indicates when watering is needed. Akadama is unique as a growing medium and is sought after due to its ability for water retention and nutrients due to its high CEC value. However at the same time it provides porosity and free drainage. Uses This small (1~5mm) particle size akadama is suited to most tree sizes. Akadama can be combined with other elements such as crushed stone, composted bark, peat, or for best effect use pumice.
