International Bonsai Master Jonas Dupuich has an article out titled “How to secure bonsai in the pot“. This is one of the best articles I have seen on how to secure a tree into a Bonsai pot. It is an in depth article that covers all types/shapes of Bonsai pots. The photos are great and the explanations are fantastic. I  have not seen some of Jonas’s techniques shown anywhere in any media format. I have added the article to the Repotting page under Bonsai Basics.
