So the wrinkling in the stem is normal? reason I am concerned is I am comparing it to the other 4 prunus that I have and they don't look wrinkledPics look good to me.
Where are you keeping it?
It looks to me like it was pushing out and maybe dried a bit or was wind burned.
I say this because I have been really aggressive with my root pruning/repotting this year. Way more than I thought possible but the timing was right and I have given them good aftercare - low light and protected from the wind. I have repotted 20+ and they are all still alive and growing well. I have only had 2 issues - bald cypress that I took down to almost nothing and a crab apple. In the case of the bald cypress it pushing new growth but I moved it onto my regular bench too soon and the new leaves dried out from some major wind. I lost some but new ones are coming. The crab apple was bitten by a light frost and some of the leaf tips were a little burned.
You are a little stuck here. The desiccated branches suggest that the root system is compromised. However once buds break you really need to provide the necessary light for the tree to begin to photosynthesize. Right now it is in an energy negative state - a lot of its stored sugars and starches are being used up to push new growth. The only way for it to regain energy is via photosynthesis.
So I would keep it in bright indirect light, but make sure to protect it from heat or dry wind (i.e. don't put it near a radiator, fan, or heat vent). If you have the room, consider creating a temporary humidity tent over the tree. A simple clear plastic garbage bag or plastic painter drop cloth, propped up so it doesn't touch the foliage, is all you need.
Thank you, do you think if I place it in an aquarium (Closed lid) would that work?
Absolutely - just make sure to give it enough light. Stone fruits need full sun if you want them to flower and fruit. Start it in indirect light until you see it actively growing, and then move it to full sun as quickly as possible.
NoDo you think I should fertilizing it as well?
Leave it alone or you're going to kill it, as it looks very weak. Get it outside, full sun, feed and water. If those runners take off and end up 12-18" long, I'd consider removing those older leaves in 4-6 weeks.
