You’ve spent weeks growing lettuce, kale, spinach, and carrots, only to discover that an unexpected cold snap is heading your way. The thought of losing those vegetables just before harvest is frustrating, especially when you’ve already invested money in seeds, soil, and garden supplies. Fortunately, one relatively inexpensive gardening tool can help protect your crops and extend the growing season.
Row covers create a protective barrier between vegetables and challenging weather conditions, including frost, cold winds, and sudden temperature changes. According to the University of Wisconsin, certain heavyweight covers can provide approximately 4 to 8 degrees Fahrenheit of frost protection under favorable conditions. However, not every cover offers the same benefits, and choosing the wrong material can leave plants vulnerable.
