It has been a busy holiday season, but I ate way too much and need to get some exercise. So even though it is cold and damp I decided to make a start on weeding the henbit ( and others) out if the path.{crushed granite).Got one side done yesterday and this morning before my fingers, ears and toes said it was time to jump into a hot bath and warm up. Does anyone have any suggestions for cutting down on weeds germinating? I was thinking of using Preen. Any experience anyone?
