We just bought a home that has several plants. I understand how to trim all but the tops. These bushes are 8-9 feet tall. Should they be cut shorter on the tops?

I would wait to prune and trim the Blueberries until late winter or early spring.
If the bushes have not had pruning for some time, I would do a light pruning the first year.
