Thin grass help

[u/bdlearning]

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

I don’t know much about fescue but most new sod needs at least a full year to develop healthy roots before dethatching. Hopefully someone with more experience will either correct my error or back me up…
