I started a chemy free lawn service in 2001. I can say that because I simply don't use any chemicals. I have tried anything I can get my little hands on in an attempt to find a product I can use to add to my lawn program. Anything being a granular, powder, liquid, voodo dance to wage war on lawn weeds. Personally I believe in tall grass, sharp blades, and just a healthy schedule does most of the work, and a little hand pulling But hey, we got to keep those customers happy and I hear over and over again they want me to put something down on those weeds! Trying to explain to someone that a chemically free lawn to compete with the neighbors chem lawn is almost impossible. You and I both understand, but are there any "natural" products out there yielding quick results to dazzel the customer? Has any body put together a bullet proof program?
