I planted in the spring of 2018 a Mount Royal plum tree. It was doing fine in 2019 but this spring it didn’t leaf out. I still can bend the branches without them breaking. There is new growth coming out on the trunk and I am wondering if these eventually would grow into new branches. Also I am wondering if I should leave all the new growth for now or remove some of it and if there is hope for the tree when and where should I cut if the top.
