I want green grass. not dead grass...

I'd say if the grass died because you let the ground dry out, it's gonna be a long road back, time-wise. I agree with the Ironite advice, it gets it dark green, doesn't burn it and doesn't make it grow 2 feet per week. Gotta be super careful of those crystal nitrogen fertilizers, especially in summer.....they'll burn up a lawn instantly. I would keep an eye on the lawn and make sure it doesn't dry out during the day. I live in the desert and maintain a lawn, so I know what you're up against!

You could also mix up some liquid Miracle Gro and spray it around with a tank sprayer.....that would probably give it a kick in the pants too.
