I just went through all of this myself when in the past month. Go into Mossy Oak biologics website. They talk about planting times, as well as recommend what is best for your area. I planted an area about 1/3 acre in size. I planted one of there products called Premium perennial as it does well in a variety of locations, it also contains brassicas which will last into the winter months when food becomes scarce. I am in a different area (southeast pa.) so they may have a different recommendation for you. Planted it 2 weeks ago and have a field full of green now. I will be posting some pictures up in the next few days. Good luck with everything.
