I have an Oak tree at my house that is in need of some serious pruning. I have only lived here for a year so I'm unsure how the tree was damaged. How should I go about pruning the lower branches to balance everything out? Do I need to wait until the leaves change colors? I've been unable to find a local certified arborist to prune it, and I can't say that I trust just any local tree trimmer. Any help is greatly appreciated
