I do overseed WR into them in Sept and let that play out into following summer. Eats up some of the excess N and helps with weed control and feeds deer thru winter and spring with early greenup.
I think this is the missing link. I couldn't agree more. I have been overseeding rye into my clover in the fall as well. The topic that's been dominating my interest most this season has been carbon to nitrogen ratios. I think I've about got it figured, and what you're saying here is the same conclusion I've come to. The way I see it, you're going to have grass. The choice is whether you pick it, or the soil bank picks it.
This is why I like rye. It comes with a vengeance in the spring and sucks up any nitrogen that could feed a rogue grass, and also puts back the carbon the soil needs to keep things working properly.
Here's what mine looked like coming into memorial weekend this year. If I could get my brother to walk instead of driving on this, it'd look even better.
I ran long on barley this year, and short on rye, so I overseeded barley into it this fall. I don't know if barley will come back this spring or not, if it doesn't the next thing I'm going to try is spreading oats into it as soon as it's up enough to protect it in spring, and keep pushing the carbon build and nitrogen use the whole season. Don't get hung up on that idea yet, it's still being thought over.
