Well, my heartfelt thanks to everyone who has put forward a suggestion on this thread. They have given me a lot to think about.
I think the next thing to develop on your tree would be to expose the root flare. And this point , you should let the branch tips go horizontal too, in order to flatten out for a wide canopy of a typical banyan tree.
Si - thank you for this comprehensive analysis, I think you have captured the direction that I originaly wanted to go many years ago. The reason for the hard cut back was in the hope of producing shoots in the right places so that I could get the branches to grow on a more horizontal level and with the shoots that are forming, I believe that I can achieve this issue. I agree that the root flare needs to be worked on next and the main issue of the bar branches may well be able to be hidden by re-growing some aerial roots in the right places.
I will try to catch up with you at some stage and maybe we can chew the fat a little over this tree. It has got quite an impressive tree in there somewhere i think.
I look forward to your visit Peter - it would be great to discuss the options with a fellow enthusiest.
Jon
