I agree. You won't have to spray twice though. Just wait until about 2 weeks before you get ready to plant and hit everything with a couple qts of gly to the acre and it'll be toast when you get ready to spread seed. Something else to think about....If your standing "hay" is thin and you spray 6 weeks ahead of planting....you won't have any hay to cover your seed come planting time. It'll do like bacon cooking in a skillet and leave you with a lot less than you thought you had.
Of course, I'm a rookie at this so correct me where I'm wrong, but I've sprayed around the house a good bit (along sidewalks, a hill behind the garden where it is hard to mow) and I get a lot of new growth a few weeks afterwards. I assume this is from old seeds that have been laying dormant even though the "seed bed" was not necessarily disturbed. This is why I'm thinking to spray a second time. Or, is the idea that the fall plot mix will choke out enough of these "weeds" so that the small grains/clover/rape etc. can establish themselves? I realize not all "weeds" are bad, but I do want what I throw out to do well.
