Determine which branches to prune. Remove dead or damaged branches first. Branches without leaves or with large cracks in their bark can become hazardous if left on the tree. Remove branches that sprout from the trunk at an angle less than 45 degrees. These branches are less sturdy. Remove any branches growing horizontally inward back toward the trunk.
Hold the clippers and trim the branches as close to the trunk as possible, starting with the dead branches. Remove badly angled branches and ones that grow inward. Do not remove more than 30 percent of the branches at any one time, as this will damage the tree.
Slice the removed branches into sections to be used as firewood or kindling, or discard with your yard waste.
