Does anyone have any experience creating bonsai using Cassia fistula? I live in 10b and would like to do an espalier using them. I recently saw a beautiful posting of a golden tunnel of Laburnum Anagyroides trees weeping over a path. I have a passage entry to my garden and I'd like to recreate a tropical version of the path using Cassia fistula. I apologize if this post seems miscategorized, but what's true for bonsai is often true for espalier.
This is more of an espalier question...
Your right about the technique of training being the same.
Most espalier are trained to a frame (or wires). In order to allow someone to walk thru it with ease the frame is going to have to be 9' tall. That's a big abor for hurricane courtry.
I would love to see it when its done.
