Pumice Medium Bonsai Soil - Cactus Soil - Alpine Soil

In stock
As low as £8.00

We go to great lengths to bring you this special Medium graded volcanic horticultural pumice. This unique pumice is not available anywhere else in the UK. This medium grade is used almost exclusively in Europe for establishing yamadori bonsai and is a large constituent in most bonsai mixes. Gives the most spectacular results when used mixed with our Chipped Bark for growing all varieties of Pine Bonsai. Used as a proportion of any soil mix this product will help to increase the strength and vitality of all Bonsai.
Lasts indefinitely and can be re-used over and over. Much better than using grit as it promotes drainage, holds moisture and is much lighter. By far the best grade of pumice available in the U.K. Only available from Kaizen Bonsai.

3-8mm mesh graded to produce an approximate particle size close to this range.

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.

When you receive your Pumice or Lapillo you will notice the material contains some degree of fines, however being damp this will bind to the larger particles. There is no need to sieve these products. Simply use straight from the bag, 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 particles will bind into the larger spaces created by bigger grains. This will create a very high percentage of micro pore spaces that will be colonised by fine feeder roots and mycelium resulting in the perfect natural rhizosphere and will ensure your plants absolutely flourish.

Kaizen Bonsai Pumice and Lapillo are ultra absorbent materials that are frost proof and will maintain their integrity for many years. Both products can be sieved out of old repotting soil, removing dead roots and other organic contaminants. Water the resulting material with Cannazym and allow to stand for several weeks before re-using.
