Hi there. I live in the central part of the county. In my backyard stands a silver maple that is probably at least 100 years old. I bought this house in 2020 so i could live under this tree. i had limbs cut back, to help her new growth. The tree seemed to be doing well. But this summer, barely half the crown flowered, and half the leaves that did show came down in the heat of June. What more can I do to extend the life of this beautiful tree?
