Best way to start lawn over with minimal weeds?
I started my 2400 sq. ft lawn from seed in November. I've used weed and feed, and various other weed killers, but I would say that the lawn is 90% weeds.
I've used Scotts weed identification service, and most of the weeds they identified can only be killed with roundup. The lawn looks terrible as I have large amounts of smooth bromegrass and barley foxtail amongst several other ones.
I want to start over, how can I best do that? But, I want to start over in a way as to kill the seeds before replanting? I'm thinking I wont plant again till Fall, so in the meantime I can focus on the weeds.
What do you think?
