I have never had a problem planting freshly-cut Plumerias right into the ground, leaves and all, during the warmer months. They take off growing right where they left off? I never used to fertilize them until this year and presently, I have a few hundred plants. They are very resilient. I really believe that the Plumies feel my passion and love for them so they are quite healthy. The only time I "callous" them is if the base gets too wet. I then cut the wet part off and let them dry out thoroughly, then replant them. I think I'm becoming a "plumeria hoarder" - my kids want to do an "intervention" but I want to start selling them off next year.Then they an "intervention" me all the way to the bank.
