Kaizen Bonsai Soil Mixes

Kaizen Bonsai Soil Mixes - Blended Soils Ready To Use

It's been over ten years since Graham first offered his special bonsai soil mixes for sale. Since that time these products have become the UK's favourite typically selling over twenty tons every year. These soil products are constantly refined and improved as better ingredients present themselves and represent the very best in quality, value and performance for bonsai tree growth in the UK today. Considering the ever increasing cost of Japanese soils and the sensitive issue of fuel usage we have now sourced 90% of our blended soils within the U.K which means less 'soil miles', less import taxes and a lower price to you!
We have been researching and testing growing media for use with bonsai for more than 30 years. Over that time we have discovered just what it takes to create a healthy rhizosphere. Roots are the powerhouse of any plant and if you want your bonsai trees to develop well and remain healthy indefinitely the soil you use is of paramount importance. The subject of bonsai soil is steeped in mystery and is a very confusing subject, especially to beginners. Misinformation is rife, especially on the internet. Our range of bonsai soils look very different to more conventional products available but after 30 years of relentless testing and research we know THEY WORK! Our customers come back year after year for these great products and everyone who has tried them agrees, Kaizen Bonsai soil mixes are second to none.

Our soil mixes are based on the very best ingredients, responsibly sourced (up to 90% recycled content). It takes a great deal of time to prepare these mixes and they should not be confused with other "bonsai compost" on the market. These are often no more than garden soil or multipurpose compost with added grit. Our new range is based on the moisture retention levels of each mix. No1 being the most water retentive fine grained soil and No3 being the most free draining and open in structure. All our soils are ready to use straight from the bag and SHOULD NOT be sieved.
