Plumeria Branches. If you want your own plumeria plant you can grow it from cuttings or severed branches from a mature plant. Also known as frangipani plumeria plumeria rubra are lush tropical trees with fleshy branches and sweet smelling waxy blooms although these exotic warm climate trees are surprisingly easy to grow they can become lopsided or spindly.
If your goal is to encourage plumeria branching thus creating a fuller balanced plant with more blooms pruning is the way to go. Also known as frangipani plumeria plumeria rubra are lush tropical trees with fleshy branches and sweet smelling waxy blooms although these exotic warm climate trees are surprisingly easy to grow they can become lopsided or spindly. Wear garden gloves while pruning and avoid contact with the white plumeria sap as it can.
I have other problems also but need to address this one first.
Keep them at a size that is easy to handle thinner branches can be cut up to a metre or so long plus have more than one tip. You can do this in sections or if possible. I live in so cal and it gets over 100 degrees. Most species are deciduous shrubs or small trees.
