More Info: Fabric row covers are lightweight blankets made of spunbonded polypropylene which is sunlight, rain and air-permeable. They offer 4 benefits: 1) Capturing warmth, resulting in healthier plant growth and earlier yields. 2) Protecting plants from damaging winds. 3) Most effective, least toxic, form of insect control. 4) Protecting your plants from light frost, thus extending the growing season. HOW TO USE: Cover your crops immediately after planting to keep insects out and to promote increased warmth. Apply the cover loosely so plants can lift it as they grow, and secure edges with Row Cover Tacks or soil. The white fabric is printed with a green logo stripe down the middle for easy centering over the row.
