The problem with rye grass is that it will continue to come up where you plant it year after year. It will out compete anything else you try and plant there later. I would stay away from ryegrass for that reason. We just planted a late plot with rye grain (elbon rye). Rye grain grows just as easily as ryegrass without the problems and is more preferred over ryegrass. Wheat will also do fine this time of year and is highly preferred by wildlife.
