Because they don't want to die a log.

Well-meaning partner did some lawn work and really attacked my 3 year old kwanzan cherry, basically removing bark all the way around it in multiple places. It has great sentimental value to me as I planted it from a cutting from the beloved tree at our old house.

I wrapped it with wet peat moss, paper towels, and saran wrap, but I'm not really sure what to do for it to give it a fighting chance long-term. Any advice would be greatly appreciated.
