Hopefully some of you can steer me in the right direction. I moved into my current home a few years ago. I have a few acres that are heavily wooded, and way overgrown with brush. In an effort to reclaim some lawn around the house I cleared all the underbrush from my front yard. I also cut down or ripped out all the small trees and left just the larger diameter desirable species. I still have a few mulberries and dead trees to get this spring. After clearing the area, I hit it in several directions with my box blade with shanks all the way down. Then I leveled the box and rsised the shanks and leveled the loose dirt. I then spread starter fertilizer and seed in early September. I watered multiple times a day, not too heavy. Grass came in in 7 days. However it never "thickened up" over the rest of the growing season. I now have a muddy mess, that I really need to be a dense lawn as soon as possible. Last frost for me is May 2nd. Pictures of the area attached. Looking for direction on how to get a dense lawn.
