I had some trees and shrubs that were a little worse for wear by the end of last summer. A couple of them hadn't been planted very long. I gave them a healthy dose of Zamzows Thrive or Save a Tree and this spring they all have healthy looking buds on them. In addition, I used the Thrive with all of my bulbs I planted and they are coming up bigger than my neighbor's who is an avid gardener, last spring she asked me what I used on my tulips. It made me feel pretty good about my green thumb!
