Thats what I had planned(9/1)... I will go with that for the un-limed 1/2 acre I plan to TnM now. I was planning on layering rye over the Oats/Peas/Radish/Clover limed 1/4 acre when the peas/Oats were browsed down around 10/1... If I plant the other limed 1/4 acre in Brassicas, How would I plant Rye there if they fail??Disking/tilling/dragging.. Method of working in the soil doesn't matter, you just don't want it sitting on the surface. Leaving on the surface will just take longer to take effect, that's all.
Late winter is when my Rye gets the most use. They dig through the snow to eat it for me. By march it's almost mud.
Your frost date is similar to mine, mid October. I'm in central MO, I typically plant my fall cereal plots around Sept 1.
