I have two large plots on a lot here in Kentucky. Both were plowed with a walk-behind last fall, and one was over-seeded with winter rye.
I've been working the non-seeded plot by hand, digging and pulling out the still-green wigs of bermuda grass that lie a few inches below the surface. This is painstaking and takes a long long time, but seems to be working pretty well.
In the other plot, the rye I seeded last year is growing vigorously. I've cut it once with a lawnmower, when it was about a foot tall. I plan to mow it at least once more, maybe twice. I mow so that the clippings cover the areas where the rye did not establish. It's my understanding that mowing will promote
root growth, and also that rye has an allelopathic effect on some other plants, bermuda grass being one of those. After another month or so, I plan to till in the rye, and may plant another cover, eg buckwheat/cowpeas.
My hope is that shade from the rye, heavy rye root growth, the allelopathic effect of the rye clippings, and eventual tillage of the whole plant will greatly reduce the amount of bermuda grass in the plot. I've not found any account of this method being tried before. Has anyone here done such a thing? Any idea if it might work?
Thanks!
