I just finished up my fourth round of applications October 7. I am on a five application plan so my next one is the "winterizer" app. of 46-0-0. I plan on putting down around 2 lbs. per thousand to get about 1 lb. of nitrogen per thousand. The last two nights we had a frost and freeze so the grass should start to really slow down, almost entirely stop for some. When should I start my last application. I was planning on mid November, but I am new at this. I have heard some people say put it down right after the grass goes dormant and some say right before. They are talking snow flakes some time in the next week or two, but I was hoping for some rain because I have 4 more large aerations I need to get done and the ground may not be wet enough now to get solid plugs. Thanks for the help.
