Trimming a silver maple
Is this the proper time to have a silver maple trimmed. I have two in the front yard of a home we moved into last year. The two trees are almost touching and are about 30' tall and 20' wide. I would like to have them trimmed as there is not much grass growing in the front yard. The whole front yard is shaded. It is the north side so I don't require the shading on the home.
