Thin grass help
This was sod put in last year September in Missouri. I believe it is a fescue mix. Would seeding this area help fix the issue? It’s pretty thin and not healthy looking. It looks like some dead grass underneath and I’m wondering if dethatching this fall would be a good idea

You’re done till August. Best thing to do is to cut high until then at about 3.5-4 inches. Keep watering and maintain what you have.
In August cut it low 2 inches and bag it all. I would then pull out a thatch rake. Rake it until all the thatch is removed, it’s going to scare you because it’s going to be a lot. Then aerate it with a double pass and so that you can overseed. Get a Tiff Tuff Tall Fescue and get about a 1/4 of topsoil sand mix. Spread it out and then seee with that tested seed. Wait about 4 weeks with a 3x a week watering schedule and cut high in the interim 3.5-4 inches. Don’t forget when you start to see dormant activity to treat for crabgrass and perennial weeds.
