We use Joshua Tree, Inc. for the maintenance of all of our plants. They are very timely! We also appreciate the way they've taken care of this very old oak tree in the back of our home. It's probably near the end of its life, but they've been very good at extending its time, doing everything humanly possible. Also, with any kind of issues (like a recent dead limb hanging down), I just have to call and they schedule an appointment to come out immediately. They are quick to answer any of my questions over the phone, and provide great quality work!
