White fountain cherry trees are beautiful flowering trees that have branches that flow like weeping willows. They grow to a height of 12 to 15 feet, and a width of up to 12 feet. Annually, the fountain cherry grows 12 to 18 inches each year until it reaches its full height. The tree is resistant to drought issues and produces red, yellow and orange fall leaves, according to Michigan State University Extension.
Snip branches that touch the ground at a joint on the limb. Leaves and limbs that touch the ground are more susceptible to to disease or molds. You can leave the limbs long and flowing as the fountain cherry is meant to be, but make sure it stays off the ground. The fountain cherry branches grow several inches in a year, so you will need to check often to make sure they don't brush the ground.
Trim out dead limbs near the tree trunk. Leave a small nub next to the trunk to insure that you do not cut into the tree. Cut part way into the branch from below so the branch doesn't split and tear. After cutting through halfway from the bottom, cut the rest of the way quickly from the top.
Trim out diseased branches with a tree trimmer or loppers depending on the width of the branch. Trim at least several inches back from the disease or mold.
Pick a length for your branches if you do not want them to hang near the ground. Trim all branches to that length. Cut at a joint.
Cut out one of two branches that have crossed each other and are touching constantly. The touching will rub away bark and make the tree susceptible to disease. Cut it out as you would a dead limb.
