I have several old plumeria plants (25 yrs old) that I take cutting from each fall, when I bring my plants in for the winter, or in early spring, after they have been dormant for approximately 4 months. These old plants were potted up in the spring and now have produced numerous tips, some with 2-3 tips 18-24" tall and one has 5 nice tips growing, those tips are 12-20" tall. Can I take cuttings below the green growth, in the old wood, allow the usual time to callose and then root these cuttings? In doing so now, I might get more tips to grow from the old wood as well as rooted cuttings. The base of the old wood is anywhere from 3" to 4" in diameter and I would be cutting through approximately 2" thick wood.
I live in NE Mississippi, and my plumeria go through dormancy in heavy plastic bags lying in my enclosed, heated porch for the 4 month winter.
What do you think of my taking cuttings this time of year?
