    What are your Growing Degree Days in Kalamazoo?
    I looked it up: 916 growing degree days--if you use a base of 22 degrees. (Same in my town, and I have a few tiny sprouts of ryegrass).
    In theory, grass seed should not go bad. However, if you planted blue and fine fescue and no ryegrass, their germination will be slower than perennial rye. I would expect sprouting of the first seedlings in the next few days.

    Growing degree days are (at Base 50) 22 for me and 25 for Kalamazoo

    As an experiment we threw some down on my own lawn late last fall. Never raked in, wintered over and now all of the sudden sprouting everywhere. TTTF and KBG (excellent high quality seed though). This up in Maine.

    I still had seed on the surface, under the snow, becuz it was never exposed to the freeze/thaw cycle... As soon as the snow was gone and the ground thawed we never got a hard enough freeze since then to 'pimple' the open dirt... today we are beginning a week long episode of 'warm rains' after the sun has spent 3 days of drying out and warming up the soil... I hope to see germination by the end of the week...

    Great observation, McFarland,,, :)

    The germination rate will go down with age, particularly if the seed was stored where the humidity was high. Some of it should germinate though. Maybe give it more time.

    Yes, seed does "go bad". Does that answer your question?

    Really? I have never had any luck getting any kind of germination without a loose soil seed bed either from aerating or from loosening the soil in spots with a stiff rake or weasel. So you threw it down on hard ground and it is now germinating?
