Hi everyone, I'm MA (zone 7) and planning to dormant overseed some sudden impact KBG that I was given a fantastic opportunity/price to purchase. I will overseed once our soil temps get down, just before the first snow.

I'll be overseeding into 19,000 square feet of irrigated turf. Right now I am leaning toward avoiding a spring Tupersan application and taking my chances with a later Dimension app once any seedlings have been mowed 2x-3x. I figure I can lean on the pre/post emergent properties of Dimenstion, then handle any huge breakouts with some reaming Drive that I have in the cabinet.

If anyone has experience with spring pre emergent timing with overseeding I'd appreciate your input. I'm still leery of the germination % with dormant seeding, but the seed was cheap and I'm excited to try something new. Thanks.
