White Reflective Ground Cover is made of white 3.2 oz polyethylene which reflects light and helps increase plant health, growth and resistance to disease. The fabric is UV stabilized, abrasion resistant and is permeable to both air and water. It is a strong, heavy fabric, which allows it to be more resistant to tearing, puncturing and weed penetration. White Ground Cover can also be used as an alternative to a frost blanket. When applied on top of plantings, it protects against light frost and cold temperatures by holding heat in during the day and by blocking wind at night.
