Premium Bonsai Compost No1 - High Moisture Retention
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.
Re-formulated for 2020. Our new formula ensures less separation of components in the pot and improved moisture retention whilst maintaining drainage and reducing weight.
Our most moisture-retentive bonsai soil mix. Composed primarily of small grain aggregates and finely graded conifer bark. This soil mix offers a free-flowing lightweight fibrous and air-filled environment perfect for the development of fine rooted species. Suitable for indoor and outdoor bonsai that need above-average levels of moisture in summer. Species that require a lot of water during the growing season will love this mix. Also if you can't manage to water as frequently as you would like in summer this fine-grained compost will keep your trees happy for longer periods between watering. Use straight from the bag, no sieving is required.
It has taken Graham thirty years to perfect our unique soil mixes. 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
