I have new customers asking for seed during winter months. They think you should seed during winter so spring rains will allow it to germinate. Well, some of this is true but you battle weeds all summer or part of the summer. Anyway, what if I power seed during winter months and hold off until 1st of May to put down Pre-M to control crag grass at which time I'll kill over BLWs too. Has anyone tried this. I have always done power seeding in the fall with great results. I have done small patches in my own yard in the spring and they seem to come in fine. I always use Turf Type Tall Fescue. My real question is will the grass come in nice and thick in the spring? I know there will be more weeds but the lawns are covered in weeds anyway.
