I have a customer that wants to plant Bermuda seed over his yard. It is about half and acre and is a mix of bermuda and centipede, but mostly a mix of different grasses and some bare spots. I roundup the yard earlier this year. He wants to aerate the yard and then put seed over the yard. I think it might work but haven't did a yard like this before. With seed being $150 for a 25lb bag I don't want to waste his money on doing the yard this way if it wont work. So I need some thoughts on if there are some more options on how to get to the job done. I would use a slit seeder but nobody rents one around my area.
