I have recently been given a couple commercial contracts on sports fields. They are tall fescue with some rye grass (which has already died out this year), and I was wondering what you guys thought about overseeding it with a turf type blue grass and rye mixture when the spring rolls around? I will be dethatching, aerating, and topdressing the fields along with overseeding. Think that this would mix well and look good? Any and all advice for sports turf will be appreciated.
