I have some mustard greens naturalized into my two yards.
They bolted and went to seed weeks ago.
Around that time I was establishing new beds with plant starts.
In one bed I scattered a bunch of the dry seed from the mustard greens.
Today I was checking on the beds.
I had lots of grass and
bindweed in every bed except the one that was filled with tiny mustard greens instead.
After weeding, I grabbed more dry branches from the greens and stripped and crunched them over the beds.
Even if I have to pull the greens because they ate squeezing out my main crops, I will at least get a harvest.
Has anyone else has good luck undersowing to supress weeds?
