I have some young silver maples and I would like to know if they are growing properly (correct leads). I have attached pictures
Two of the photos show trees with the main trunk divided into two almost equal trunks, with a rather narrow angle between them. This configuration will likely result in a weak joint and is an invitation to the possibility of having one of the trunks split off the other one after many years of growth. Silver maples are short lived; so, it may not matter, because the trees could be senescent by the time that the trunks are heavy enough to split off.
