about how much would it cost to put patches of grass?

Question

around 30 feet by 30 feet.

Answer 1

If you're talking about sod, it will be about $200 per pallet of grass, you should need one maybe two pallets

Answer 2

You doing the work? Figure anywhere from 30 to 50 cents a square foot. Sorry, I'm not up on sod prices these days, can't have gotten too much higher. Call for the price per roll, how much a price will cover, will you pick up or have delivered...extra charge. Don't forget your soil prep includs rototilling the area (rental), adding starter fertizer and organic ammendments, renting a roller, etc. Factor these in and price could be another 50% higher.
