Try covering it with black plastic for a week or so. That should kill it off, then till it again alot.
I thought cover crops were supposed to be tilled over right before they go to
seed so that the nitrogen is not lost on creating the
seed.
Although I've been a successful vege gardener all my life, this past winter was the first time I followed the incessant advocacy for a winter cover crop. I planted a beautiful, healthy crop of rye.
Problem is that the rye appears to have been way too successful and too healthy! It created huge root systems and a very heavy, hearty thick sod. I mowed and tilled it, which was a real challenge; it was like breaking into a long-established lawn of thick crabgrass! I keep tilling it, but it is not dissipating away. With all these healthy roots, I expect most of it will continue to grow.
What am to do with it? Do I just plant my veges among all this heavy thatch and thriving root balls? To rake them out would defeat the purpose of the winter crop a well as be an enormous labor task.
Your advice and experience will be appreciated.
