OK, I too cleared about a half acre and got my ph as it stated on the bag, and spread seed(imperial clover) , culti-packed it ,within two weeks it began to take off wonderfully, I have left the area alone with little maintenance. and last weekend I saw it and was still nice and thick ,but covered in weeds,, and (3-4'') tall on average,, was thinking of spraying it with arrest,, but you guys are just mowing it? yours look amazing!! HELP...
