Tell me about this procedure, because I'd love to speed up seed germination!
The floor WILL get stained from the tea, by the way, as the seed dries. I let it dry for a couple of days, stirring it from time to time so that it would dry evenly. Then it's ready to throw down! The way the writer of the book from which I got this idea, "The Impatient Gardener" put it, "when you put this grass seed down you'd better run like hell because that's about how fast it's going to grow." He was right, too. It too less than a week for this seed to sprout! I think it must be the tannic acid in the tea that helps loosen the husk and lets the sprout have an easier time coming through.
I watered the area I was seeding very thoroughly, but remember not to over water, after the seed is down, or it will end up floating on the water in clumps, and when the water is absorbed into the ground, the seed will remain in those clumps. If you can just dampen the seed with the sprayer attachment a couple of times a day, it will be up in a week! We'll have to wait until its about an inch and a half high before we can mow again, but I had had Joseph mow just before I put the seed down, so the rest of the yard is not ungainly, yet.
One thing I did with the overseeding after the first batch had clumped up, was, after I sprinkled the seed, I walked on it to tamp it down into the soil. That combined with VEY light watering should solve the clumping problem.
