I'm so happy with the way these hedges are shaping up, this is the second trimming I did yesterday with the hedge trimmers. When I did the first trimming in May, I really cut out, and off, alot to shape them better. Even the parts that had nearly died during the cold winter three years ago have come back great. A little wonky along the tops here and there but I call that "the natural look". ha Also I don't think you have as much control with power trimmers like you do with scissors, but - cuts time in half. I started at 8:30a in the morning before it got hot and finished at 11:30a. There are three more pieces to do but they are much easier than the borders and I'll do them later. NOT today, it's noon and it's already 90 degrees.
