    I'm hearing anywhere from 2-3 lbs per 2000sqft to 6-8lbs per 2000 sqft. I'm in CT and using a pr kbb(improved) mix. I'm also thinking of adding some fescue.

    Depends...how much perennial rye (use at 6 lbs per thousand), and how much KBG, use at 2 to 4 pounds per thousand. For best quality add no more than 15 percent perennial rye--otherwise the rye crowds out the blue in the first month, as it comes up 2 weeks sooner. Rye has a bigger seed so fewer seeds per pound. KBG has about 2 million seeds per pound. Not sure --several complications.
    Is this a new lawn? Overseed? Renovation? Shade? Sun? Sportsfield? Irrigated?

    As the title says overseeding, sun and shade.

    Matt,
    Why are you overseeding? Thin? Thin spots? Disease? Shadeout? Burn out from last year? Correct any problems you can. Is this a high-quality lawn--or more standard lawn?
    I prefer a mix high in top-quality perennial rye, using a slit seeder. I am concered that bluegrass would not take hold in a high enough percentage to make any difference. And if the bluegrass is a dark-green type you might get green spots. You never really know how much took. A top rye like Gray goose, or Silver Dollar would be a good bet. Vigorous seedling. Disease resistant. Suited to northern states.

    Thickening up existing lawn and a few sparse area's. It was originally seeded with 33% KBB,33%PR(improved),33% Chewings fuscue. There's KKB there but I'd like abit more. I prefer spreading grasses when possible. It's sun and shade area's. So it sounds like slice seeding is a better option.
