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 over plants with low growing points like summer squash or lettuce so their leaves can lift it as they grow. For plants with higher growing points such as peppers, use supports like wire or Quick Hoops™. Secure edges with soil or sand bags. The white fabric is printed with a green logo stripe down the middle for easy centering over the row. Also included in this category are netting for insect exclusion without thermal increase, and shade cloth for use over Quick Hoops to reduce ambient temperatures for heat-sensitive crops.
