Row covers are a great way to help protect your crops from a variety of environmental pressures and they come in a wide array of shapes, sizes, and weights. Row covers are most commonly used as either an Insect Cover to protect crops from pests or as a Frost Cover in order to protect crops from low temperatures. Frost cover can be helpful in protecting from rapid temperature drops, high wind, pests, and low temperatures. You can also use row cover to shade plants and protect them from intense sunlight.
