We started planting a willow fence along one edge of our root vegetable garden. Quack grass is a rather large “opportunity” for us! We theorized that if we dug up the grass inside the garden, and put some sort of barrier on the outside, we wouldn’t get as much coming in. Plus, we just really wanted to have a patterned willow fence! We have a LOT of willows on our farm. Should be a good experiment. We may regret it in the future but I want potatoes, not grass..
