I have attached 5 pictures of a potential customer's shrubs. These shrubs have not been trimmed or maintained in any way since the house was built around 10 years ago. They are wanted them shaped up and cut to around 3' tall or just below the bottom of the window. I have been doing shrubs for awhile but never had to cut that much off to achieve satisfaction. How would you all go about doing this? Will it hurt the shrubs to take off that much all at once? Any suggestions would be appreciated.
