Row cover
From Wikipedia, the free encyclopedia
In agriculture, row cover or cloche is any material used as a protective covering to shield plants, usually vegetables, primarily from the undesirable effects of cold and wind, and also from insect damage. Commercially available row cover is usually a lightweight synthetic, such as clear plastic (polyethylene) or spinbonded polyester. It is placed directly above rows of crops on a supporting frameworkâoften, on wire hoops to form a low tunnel, and usually left in place for several weeks until crops are well-established.
Floating row covers are extremely lightweight versions that can be placed directly over plants, without need for overhead support, instead being simply anchored to the ground against wind.
