The Planket is a plant blanket that helps protect your valuable plants from frost, sleet, snow, and cold winds. This rectangular shaped Planket measures 10 feet by 20 feet & covers up to 200 square feet and is made of spun-bonded, nonwoven material. There are 14 built-in grommets along edge to secure the Planket to ground (best secured with the Planket Landscape Stakes). The lightweight, but durable material allows plants to breathe. Goes on in seconds and folds up nicely for easy storage. Available sizes include the 6 ft. Round, 8ft. Round, 10ft. Round & 10ft.x20ft. Rectangular.
