Directions: Row covers are best use over crops with support hoops to hold the row covers over top of the crops. There are many different types of fasteners that are sold on the market to hold down the ends of the fabric but we recommend using any of the following: sandbags, pots filled with soil, pipes or wood. We sell a row cover support that works great over crops, link here.
