The row cover fabric can be anchored down with a light sprinkling of soil along the edges. Since I live on a "Pile of Rocks" I have also use rocks. I use prefer to use "fabric staples" recycled from wire hangers to hold my fabric down. If you are interested I will post instructions on how to make the hangers.
