Heavyweight row cover for frost protection provides protection down to -5°C (23°F). It can be used over lettuce, spinach, strawberries, and winter squash in the fall. Placed over heat-loving vegetables such as tomatoes, peppers, eggplants, squash and melons, it can make a 2-3 month difference in cool summer areas. When using over tall seedlings, support the fabric on hoops so the plants do not bear weight. Heavyweight Row Cover is a 1 oz/yard, spun 100% polypropylene that makes a warm environment for the first flowers on tomatoes, giving an earlier fruit set, but will not protect them from blight. It can also be used over potatoes and corn for the first 2-3 weeks after planting to speed sprouting. Doubling the fabric gives more frost protection but it transmits less light. We recommended for wrapping it around shrubs and trees to protect them from winter winds. Heavyweight row cover allows 70% light transmission.
