Our sturdy cover is made of woven green polyethylene to protect your shrubs and small plants from snow during the winter. Our product is ecological, and reusable year over year, versus the competitor. Our shrub covers have a solid anchoring system and will not need a brick to weigh it down. The fabric is secured over a flexible fiberglass frame and includes 4 plastic stakes for anchoring it to the ground. Folds up and dismantles easily for storage, so it can be reused year after year.
