Kaizen Bonsai Soil Mixes - SHOHIN SOIL MIX IS BACK!

We are very excited to be able to offer our new and improved Shohin Soil Mix which has been absent from our range for too long now. The new mix is cleaner, more closely graded and significantly improved in respect of it’s boi-activity and nutrient holding capacity. Important for bonsai growing in small pots.

It's been nearly 20 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 40 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 70/90% of our blended soils within the U.K which means less 'soil miles', less import taxes and a lower price to you!


GREEN DREAM products are without doubt the UK’s most popular organic fertilisers for bonsai trees. We sell many thousands of products annually and after 30 years in the market our fertilisers are trusted by huge numbers of customers across the country. We are very pleased to present the latest additions to our range. These are 100% organic, natural AND UK produced and all are in stock for next day delivery.

NEW! Japanese Made Quality Stoneware Bonsai Pots

Nobody makes quality products quite like the Japanese. Quality materials, passion and attention to detail are a given when purchasing Japanese manufactured goods. For the discerning bonsai enthusiast that demands a little more than the next guy, we are pleased to offer this range of bonsai ceramics not seen in the UK for decades.

Graham got fed up with sub-standard ceramics and poor quality and so we have stepped up and imported these exceptional value Japanese bonsai pots. Whilst they may not be the quality of artisan-made and signed 'Tokoname' bonsai pots they are absolutely the best quality available at anything up to two or three times the price.

High fired vitreous stoneware is supremely frost resistant. We feel the consistency, high-quality finish, adaptable colours and attractive design of these pots coupled with amazingly good prices make the range unbeatable.
