NEW! Premium Bonsai Compost - Shohin Soil Mix

NEW! Premium Bonsai Compost - Shohin Soil Mix With Biochar

Finally back in stock our popular shohin mix is back new and better than ever.

The new mix includes Biochar and a whole host of amazing fine graded absorbent aggregates which will not break down by frost or oxidation. This mix is suitable for most species that make shohin sized bonsai trees from maples to pines. If you prefer a more closed soil mixture we recommend adding Ugro Coir in small quantities up to 10% before use.

Small bonsai pots offer a challenging environment in which to cultivate trees. Keeping enough moisture in such a small pot without water-logging the soil is a very difficult task. Our shohin bonsai mix achieves this admirably and also has a high cation exchange capacity (nutrient retention). A large amount of moisture is held within the soil particle, whilst excess water drains away. As the soil dries moisture is released from the soil's particles to be taken up by roots.

We take a GREAT deal of care and time in preparing and grading this excellent and very special soil mix hence the price. The high performance ingredients are painstakingly graded by hand to ensure the ultimate quality and consistency that, ultimately, guarantee optimum results for all trees growing in small pots in the range of roughly 3" to 11". For pots smaller than that size use our No1 soil mix and above it use No1 or No2 depending upon the moisture holding capacity you require. Obviously you can use this mix for any size pot but the alternatives represent better value for money.

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.
