Graham Potter's bonsai video series are a firm favourite with many enthusiasts, myself included. Graham and his team at Kaizen Bonsai have been very busy recently, and it has been a while since a new video was released. On his blog, Graham has just promised us a new video, due within the next couple of weeks. He has also teased us with a photo of the featured material. It should be a good one!
