the potted one should recover and branch from 1 of the old leave nodes. I use cinnamon on the cut ends, or like rox said dap or liquid tape. My first attempt at rooting started in Oct with several cuttings. And I have 1 cutting that is sitting until spring from 2 weeks ago. I pray I don't fail.

Only thing to add to the great advice above would be to wait and see. In the near future you will need to monitor the area where you caulked or sealed for water intrusion under the sealant. It happens when the plant starts growing again and the shape of the cut changes enough to where the elastic material pulls away from the edges. Now you have a situation where water can get in there and it doesn't dry out. So please think of it like a band aid which is used for a period of time until you can start cleaning up the damaged area.

Below is a picture of a Dean Conklin with storm damage. It was several years before I realized the caulking in the wound was trapping water so I removed it and cut a notch as a temporary drain until I was ready to prune it. In this instance I removed the damaged area entirely for aesthetic purposes. But in other cases I removed the Cambium and Wood (outer two layers in this image) back to the callus on the Pith (center part) and got a nice clean area which the Cambium will grow over in a few years.

Only time will tell. I will update on the process ..... if spring ever gets here! lol

I have 4 plumeria I rooted from sticks, they came from Los Angeles area from a guy whos mother has a tree. They were covered with spider mites, a good spraying of rubbing alcohol took care of them. After cutting at a 45 angel, and curing for two weeks, I put them in 1/2 gallon black plastic pots, using cactus mix plus a handful of peat moss per pot, only half full of the mix. NO WATER. It was like waiting for a chicken egg to hatch!! Finally I could see life, they were all getting little nodes on the tips, I gave them 1 cup of water once a week, no fertilizer, left them outside in full sun as long as I could. Mid Sept. they were inside in a south facing window still adequate light. By December 1 the Christmas tree went up, so Plumeria and Pomogranet tree went down stairs into a new environment!! Yikes, I kept watering the plumeria, I put a 25 watt curly light on them, soon the leaves all turned crispy brown and fell off. I realized its not a good place, and read up on how they need a rest period. They have been in the pots, in a cool room for about 2 months. I check on them regularly. They have the little nodes (leaves) starting to peak out. We have 1 ft. of white snow on the ground, and insufficient daylight for them. SOS..do I put them in gallon pots with new soil, add a fertilizer? give them light..Newbie with plumeria showing a second season of life? I'm thrilled they made it, but unsure of what to do now? advise is welcome..Thanks Barb in the Far Northwestern part of Montana watching it snow. you can email me at barbmelichar@gmail.com

Total newbie myself.... but i would say they will still all be ok until spring hits. You can have them in a window now & wait for the leaves to grow - once they are big enough then give water. While they Leaf nodes i would wait.

I had cats snap off two stems of a rooted (red) cutting. I put the two stems in pots with old potting soil..sort of depleted. They got a little wrinkly like yours and I though they were goners,at the very least not rooting.

But now I see even in mid winter normal tiny leaf tips waiting for warm weather or at least longer days.

So,dont give up on them.

Oh,and the original plant? its sprouting new branches like 2" from the top of the soil line.
