I never worry about my plumeria when I take cuttings. The cuttings will all go into the greenhouse because rooting them is done in dry perlite. The rooted plant that was cut, well, she stays outside in the weather and full sun. I have never put those plants that have had cuttings taken in the shade. I have never used wax and never even heard of it being used. Just let those cut ends callous. Everything will be fine.
That's just the way I do it and apparently I don't do a lot of things that others do.
