Hey all,
Recently planted my Punakenikeni tree in ground.
It has been doing well and exhibiting new growth.

My two questions are

is it way too close to that structure? Will I be looking at an ongoing problem cutting back, will the roots affect anything?

2 and secondly, I am impatient, anyone have a best guess on how long until I should be seeing potential flowers?
