1 Day A Year Bonsai Trees

It’s a beautiful early spring day and the sun is shining here at Kaizen Bonsai world headquarters. Just finished watering my trees for the first time this year and the garden is ablaze with the beautiful and welcome sight of spring flowers everywhere. For the first time in months I find it a joy to be alive. It’s been a very long hard winter and I for one am pleased it’s all over (for now at least).

This is the first morning of 2026 that I have had a minute to relax and think about anything other than getting boxes out of the door. Richard can handle todays workload so I thought I would pen a quick note to let ya’ll know i’m still here beavering away. From our first day back in January we have been buried alive with orders for which we are all very grateful. The support of our lovely loyal customers keeps our little family afloat and we are eternally grateful to every one of you!...

Seasonal Care Tips For Bonsai

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.

  • Elaeagnus after defoliation

    1 Day A Year Bonsai Trees

    One particular favourite of mine is this elaeagnus, it’s an absolute thug, grows like a weed and throughout summer is all but impossible to restrain. However come early spring it needs to be defoliated, this takes typically four hours of intense work.

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 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
