I know that for some topdressing is a naughty word. Here is why I think it may help my situation. We have a soil base of about 80% sand. The lawn is SUPER dry, especially in the summer months, and has a few bare patches where the sod just didn't stand a chance. I am thinking about cutting the current grass super short (I don't know 1" maybe), seeding it well, and topdressing with about 1/2" (or whatever you suggest) of peat moss. What do you guys think?
