Preferred Lawn and Garden is the best place to go to for your lawn needs. They are very knowledgeable in any advise you would need. I went to them in October 2012 about my lawn because all summer it had a lot of brown spots because of the heat. After taking their tips and yard supplies from them my yard was the ONLY green lawn during the entire Winter. My neighbors all asked how did I keep it so green this winter, It was because of Preferred Lawn and Garden in Kernersville, NC. Today, March10, 2013 my yard is still the only green yard in the neighborhood. They also have the best fertilizer and grass seeds. Thanks Preferred Lawn and Garden you are the best.
