Rambling Flummery & Tidings of Comfort and Joy.

As we round out another year i'm sitting here in the gloaming of a late December afternoon staring at an empty text box and a flashing cursor. At this precise moment I have nothing to say though, i doubt that will last long. A little Rambling Flummery & Tidings of Comfort and Joy are therefore in order.

My last post in October was, for me, quite a positive one which many folk seem to appreciate. Following the year I have had it's best I keep it that way, focus on the positives because the negative side of the scale is getting a little heavy of late...

Caring for bonsai can be a confusing subject, especially for beginners. Here at Kaizen Bonsai we believe successful bonsai comes from understanding the simple horticultural principles that sit behind every technique. With that in mind, Graham has written a collection of articles to help keep your trees healthy throughout the seasons. Each one is built on decades of hands‑on experience with thousands of trees in real British
weather conditions.

So whether you’re managing winter protection, spring repotting, or thinking ahead about fertilisers, our care guides will help you make the right decisions at the right time.

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.

Customer Testimonials

  • This week I've received two deliveries from Kaizen, both were a prompt response to my orders. Both were delivered on time, both were very well packaged. Of the two starter pines, one had the unexpected bonus of being twin trunked. As Graham described, the little juniper is a beauty. Thanks to all. As someone newish to bonsai l would like to thank Graham for being the sort of guy who is happy to share his knowledge and experience with all who come looking. (video tutorials, blogs etc.) He seems to me to be one of life’s natural teachers. Cheers to all at Kaizen. T.S U.K

  • Hi Graham & Catherine, The tree arrived safely and really excellent packing don't how you do it. The tree looks fantastic but then so has every purchase from you guy's I really enjoy what you offer to us bonsai nut's. Big thanks to all the team. N.G - U.K

  • Hi Kaizen, Cork Bark Oak arrived safe and sound, a lovely tree professionally packed as always. Once again you’ve shown how you are the best, and for someone like me who has only been involved with Bonsai for three years or so, Kaizen has enabled me to avoid many of the pitfalls which catch out many beginners. Sincere thanks and best wishes to you all. N.B - U.K
