Q.Are jacaranda trees deciduous?
I bought a small plant, about 2.5 inches, in Madeira in June, it is now 9 inches tall. Some of the lower leaf branches have fallen, and now some of the leaves on the newer branches are dropping. I also want to limit growth to a pot, albeit a fairly large one, where and when do I cut the main trunk to create spread?

The tree is only evergreen in the warmest climates. Hardy in zones 9-11, the jacaranda tree will drop most of its leaves in cooler areas or during dry spells.
Your tree is too small yet to prune I would say, but here are instructions. The pruning article says to select a central leader and cut out competing branches. The spread comes from major horizontal branching in the middle of the tree.
