Premium Bonsai Compost No2 -General Purpose Mix with Biochar

Our 17L soil package is now delivered in a cardboard box lined with a thin plastic bag, don't remove the bag, use direct from the box.

Hundreds of tonnes sold over the last decade. The UK's most popular pre-mixed bonsai soil used by hundreds of enthusiasts for tens of thousands of bonsai trees NOW CONTAINS UK PRODUCED BIOCHAR.

As close to a ‘universal’ bonsai soil mix as it is possible to get! The perfect blend of high-performance aggregates, hand graded bark and Biochar that combine to make an exceptional soil mix that will produce top results in a wide range of situations. Species that require a rich nutrient retentive but free-draining soil will love this mix. A great medium for establishing collected trees and container grown bonsai stock plants. This mix achieves the difficult task of holding plenty of moisture whilst still allowing good air circulation around the roots. Over-watering is not really possible and yet the soil holds plenty of moisture and air to allow your plants to thrive. The addition of UK produced Biochar elevates this mix to new highs!

Use for large elms, beech, hawthorn, maples, myrtle, cryptomeria, bamboos, broadleaf shrub varieties like privet, crab apples and flowering trees, in fact, most species that require a moist well-ventilated medium. We also recommend this mix for use with fine foliage juniper varieties like Itoiogawa, Kyushu and Sabina.

Use straight from the bag, do not sieve.

It has taken Graham thirty years to perfect our unique soil mixes, a process that continues every day. It's possible that a third or more of the bonsai trees in the UK are planted in our soil products, we sell hundreds of tons a year. We don't sell hastily composed mixes that are untested. Please respect this effort and dedication and don't ask for the recipe.

"After spending the last 18 months experimenting with Kaizen soil mixes….I have to say I’m mightly impressed with all the varieties I’ve used.

Just done a repot of 4 young Japanese larch trees…..One was previously potted 12 months ago with Kaizen No: 1 …another with No: 2….3rd with Akadama ….and the forth with another heavily organic mix that I purchased elsewhere a few seasons ago.

The growth and quality of the tree roots that have been in Kaizen mixes looked outstanding compared to the others that were not!

Generally speaking all my bonsai that went in Kaizen mixes have done extremely well with healthy vigorous growth." S.P - UK.
