Begin by reviewing general pruning tips, then learn how to prevent tree rot with collar cuts. Next, learn how to work with very young and very old trees, as well as hard-to-prune ornamental trees, such as the cherry tree and Japanese maple. Finally, learn how to vet an arborist to handle larger tree pruning jobs.
