Single-trunk, leggy tree. How to prune?
I have a 24 month old plumeria I grew from a slip I received when visiting my daughter in Hawaii. It originally formed two branches early on, but when it was about a year old, our cat accidentally knocked it over, breaking off one of the branches. It now has a long single trunk that leans. It is just starting to flower for the first time. When they finish, I don't know if I should prune it, and if so, how? I keep it outside during the summer and keep it in a bright window during winter. The lower leaves have fallen off during the winter, with two lower ones hanging on after a hail-storm which shredded them some. Growth at the top seems fine. Any suggestions on pruning or not pruning? )I've thought of re-potting it so it stands more upright.)
