Hello, I'm new here, found this site a few weeks ago. I live in Southern Minnesota. I have about 4000 sq ft of turf. I don't know what kind of grass I have. I've lived here for 8 years. I started mowing a little higher (3 1/2 inches) this year. I live on a corner and have alot of boulevard. One section of boulevard died out this summer and is overgrown with weeds, mostly wild violets. I don't know for sure why it died but I suspect lack of watering. The area in question had a tree shading it for many years until this year, tree was cut down last fall. It could have also died from grubs but I've never had a problem with those before. I need to fix my lawn. Two weeks ago I sprayed this section and spot sprayed the rest of my yard with Weed Free Zone. I think I got a pretty good kill. I also spread winterizer fert. the same day. I know it's too late in the fall to start new seed now. We're starting to get lite frost at night here now. Daytime highs are in the mid 50's. What about dormant seeding? I bought some Lesco double eagle seed yesterday at Home Depot. How long should I wait to overseed for dormant seeding? How should I prepare the bare spots and the rest of the lawn? The local rental place has power rakes and core aerators for like $24/2 hours. They don't have a slit seeder. Any help would be greatly appreciated.
