Unroll and place directly over transplants or planted seeds for “floating” installation, or over #9 Support Wire, Hoop Loops, or Quick Hoops™ to create a low tunnel environment. To anchor, secure with Snap Clamps, Row Cover Hand Pegs, sand bags, or dig a furrow along each side and cover the fabric edges with soil. If your plants are insect-pollinated, it is advisable to remove insect barrier when plant blossoms open, to ensure adequate access by pollinating species. Remove row covers if temperature exceeds 90°F/32°F inside the row cover.
