I want to better my knowledge on the application of overseeing with winter rye. I have noticed that the method we are using, isnt producing a quick establishing turf, and has taken an additional month to look like how the other professional companies are applying it. Our method. Scalp the lawn, as close as possible. Bag clippings, blow clippings off with blower when needed. Apply 21-0-0 after lawn has been cleaned. apply perennial rye at a rate of 10 lbs per 1000 sq ft. 50 lb bag over 5k sq ft. 2 months later or so after seed has been established, and we've cut it a few times, we apply a 18-24-12 fert with Pre M. month or two later we hit it again with a 21-0-0 and it looks great. just had a hard time getting it to come up this fall. water in 4 minutes a run time, 3-4 times a day. most companies here do it while it is still quite warm in september. please dump your knowledge on what I am missing, or a better way to do it. a way to scarify the soil would be awesome, but seems like an expensive practice. thanks for your help.
