I have two plumerias. One of them refuses to branch. I have beheaded it a number of times, but each time just a single branch arises from below the cut. Is there any way I can get anything but a tall skinny plant?
Stop beheading it and just remove the very tip of the branch you DO have and that is where the apical dominance is, meaning there is a hormone which is halted at the growing tip, forcing growth lower or elsewhere on the plant for a time.
