@luckyzl230!! I am the least person to ask for advice though a true lover of plumeria. But I wanted to add my welcome. I seem to do OK with cuttings but rooted plants have been a problem for me for some reason?? I have two that I brought home from Cailf. in soil and they are doing well. But I have tried twice to transplant a bare rooted plumeria only to have both die.
Let us know how your newest plants are doing. Stay cool in Sact'o!
