I have had Scotts taking care of my lawn for quite a fews years now. This year it has patches of brown and weeds. I requested a specialist from Scotts come look at it to determine what I /they needed to do. Someone came out within 2 days which was a great response, but all that I received was a note saying that there were no weeds, but were tree saplins and weed killer did not get rid of them..only pulling by hand would work. that's all! nothing about the brownspots, the clover or morning glories in my yard...gezz thanks for the professional response Scotts..so glad that I have the guaranteed service.
