Here is an example of Cover Cropping in Walk Paths. This is a mix of hairy vetch, field peas, winter rye, and alice clover. This mix suppresses weeds nicely.
And a little bit of a close-up.
Cover cropping in walk paths does more than suppress weeds, it adds to the soil quality by biology in the root mass, legume root mass, in particular, fixes nitrogen in the soil, and prevents soil loss due to erosion.
And - It looks good!
Great idea. I'm going to order some organic cover crop seed and try this too.
