That's not the only tall, leggy plumeria you have in the picture, Cheryl. Even if you cut it in half, you are still going to have very tall plants. If I were doing it, and I'm no expert here by any means, the first order of business would be to get control of the legginess of those plants. To do so I would make a cut perhaps at the 18" point above the soil line. As likely as not, you'll get branching on that already rooted section. Then I would continue to take 18" sections until I ended up with the top branch 18". I can't see where the branching goes on the Riviera so don't know how long the branches/tips are. If I have branches/tips say 24-30" long, I have no qualms about cutting those tips in 12-18" sections. I prefer multi-tipped plants and I like multi-tipped plants that are not overly top-heavy.
Of course, I have to bring everything in in the fall, so not having extremely tall plants is a must for me. I don't have the advantage of leaving my plants out year round.
