I had a tree taken down and the stump ground up. I cleared a majority of the tree mulch and laid top soil, seeded, and put some hay on top. It's been a couple of weeks and the grass is growing in really patchy. It looks pretty bad. It's been extremely hot lately, so I'm thinking it's probably not getting enough water.
My question is: should I rake up the hay, dig up what's currently there, and start from scratch? Or should I seed on top of the existing patchy grass? (I'll be sure to water more often this time around.)
