Hi, Maryland Extension. I'm wondering if you can offer some advice in potentially grafting some branches from one area of a lilac tree to another area of the same tree? I've attached a photo of the tree. Several years ago, quite a bit of snow slid off my roof and sheared off the branches on the right side of the tree. I let the tree go for a few years to see if small branches might sprout on the side of the tree that was sheared off. Thusfar, there has not been much growth on the bare side. Might it be possible for me to take some branches from the left side and somehow graft them onto the right side to eventually give the tree a more balanced appearance? It seems like spring would be the time to attempt this grafting approach.
