Best time to trim branches on a Maple?
The neighbor's maple tree (I think it's a silver maple) overhangs our backyard. We have a ordinance that says we can trim trees that overhang onto our property even though the tree itself is on someone else's property so I'm safe there. The limb in questions is about 3-4 inches in diameter and is the middle limb of 3 that branch off from one juncture It's small enough for me to handle myself. My question is when is the best time of year to remove a limb of this size? The reason for the removal is for looks and to let in a little more sun for the grass.
Thanks for the help.
