I used unhulled bermuda for quick germination on my dam and around the pond. When moisture is applied I have had it germinate in less than one week. I recently added some to bare spots that are more clay than topsoil so I will see if it comes quickly. I'm not sure what the result will be with the slightly cooler weather we are experiencing these days as well as the shorter days. You may call someone that does the spray application. I have no idea what this might cost but I have seen it hold down erosion in new property developments. It has a mixture of seed, fertilizer and paper (paper holds everything in place). Another idea may be to plant a seed oat on it. my experience with oats is they come up very quickly and they have larger blades than rye. A combination of bermuda and a cool weather seed may me in order this time of year. Good luck with stopping the erosion. If your area is like mine, the rains we've been getting have been steady but not downpours.
