My property is a little larger and I don't have the time to take care of every aspect of my garden. I picked Snyder's Weed Control out of the phone book quite a few years ago. The tech explained everything about the service to me. He said they guaranteed the service for a year. Since then, they have been coming out annually to spray my garden. I rely on them and I have not been disappointed. I believe others could rely on them as I do.
