Pin oaks are beautiful trees with a pyramidal shape that require minimal pruning. Most pruning will be to remove low branches that are in your way, branches that may be brushing up against a building or diseased or damaged branches. Prune pin oaks during the dormant season, from November through February, to avoid any disease complications (such as oak wilt fungus). The required tools will depend upon the size of the branch and the location on the tree (for higher branches you will need to use a pole pruner/saw).
Determine which branches need to be pruned. Make sure that the branches you want to cut will not destroy the pyramidal shape of the tree. Step back and look at the tree from all sides when determining which branches you are going to prune.
Locate the collar and the bark ridge on the branch you want to remove. The branch collar is on the underside of the branch, where it meets the trunk. The branch bark ridge is on the topside of the branch, where it meets the trunk. You want to leave these areas intact, cutting just in front of them. This helps the tree to heal quickly.
Using the proper tool (depending upon the branch size) make your cut. Follow the same procedure for each branch you prune. Cut up large branches up for firewood. Dispose of smaller branches.
