Hi Rod and James
Thanks for the compliments.
Jacarandah are not the easiest to maintian, but they are not hard

They grow well and backbud readily, and the mature bark is to die for.
To develop the trunk, let it grow madly and then cut back hard to force backbudding and give taper. I have done this 4 times on mine to get the trunk as it is.
When you want to develop the branches, Let the new shoots lignify and then wire them to shape. ( get used to wiring cos you need to do it on all shoots. The new growth wants to go to the sky so needs to be wired down.
I let my new shoots get to 2 sets of leaves ( 4 leaves) and then cut back to the first set. The first pair of leaves are always smaller, and when you cut back to them they will not grow much larger. As they get old you can remove them as they look tatty. New one will replace them.
When you cut back you will get 1 new shoot at the base of each leave. Let each extend to 2 sets of branches and then cut back. You can leave a litttle longer and wire them before removal to build ramification.
I get die back randomly over the tree, so just cut them back to live bark and they will reshoot.
