Thank you
@Taramaiden. I'm still here. The original plant in question still has few branches but flowers profusely so I am not complaining.
I am going to try this method on a plumeria pudica that has sever upright growth with few branching. I have cut it back 4 times so far and last year it reached almost 7 ft. pretty much as a single trunk. It still flowerted beautifully on the new growth however. I would love for it to branch. I have my clean knife ready for tomorrow!
