what can I do about bougainvillea topiary tree?

Question

I have a bounganvillia tree and brought it in for winter. Well, now it keeps losing leaves and then they will come back. Is there maybe a way I need to trim tree? Can you help?

Answer 1

It is trying to go into dormancy. The lower light and lower temps are giving the signal to go to sleep. I would actually not worry about it too much. When you put it back out in the spring, it will spring right back in a very short period of time. Next year, you may want to just allow it to go completely dormant for the winter.
