Something like BioLogic Green Patch Plus with it's mix of wheat, oats and brassicas would be a GREAT option for a fall planting. It also does better in less than ideal soils. In fact, I'm going to be planting a couple acres of this stuff myself in the next few weeks. I've also heard lots of good stuff from Buck Forage Oats and now BioLogics new Trophy Oats is said to have an even later, longer lasting blend of prefered oats. Lots of good stuff to plant this late. Good luck
