Have any of you guys had good luck with winter dormant overseeding? I did a complete renovation of my lawn with turf type tall fescue and want to fill in the few thin places. Also have several customers with thin areas of lawn due to shade and/or pets. Theory is to go out in January and broadcast seed and mother nature prepares the seed bed through the freezing and thawing of the soil. What is your experience on the % germination in the spring? I live in Ohio if that helps. Local radio guy Denny Mckewen swears by this method.
