Is it too late to seed large bare spots in the lawn? Would it be better to wait until Spring? If I wait until Spring should I return the grass seed I recently bought, and buy fresh in the Spring? Thanks.

If you can do it now through October 15th, that's what we recommend.
Fall is a better time to seed than spring.

Thank you very much for the excellent info.
