As summer winds down and the first hints of autumn arrive, gardeners face the challenge of protecting their late-summer vegetables from frost. Many summer gardens are beginning to slow as temperatures drop, signaling the end of the growing season for crops like tomatoes. However, gardeners can extend the life of their plants with a simple tool: row covers. These are sheets of sheer fabric, often sold as "row covers," that can be draped over plants to provide warmth and protection against cold weather.
Row covers can be used in two main ways: floating or hooped. Floating covers are loosely draped over plants, while hooped covers are attached to flexible frames made of bent PVC pipes or purchased hoops. The hooped method is better for protecting delicate plants, as it prevents the fabric from crushing stems and leaves. These covers are useful not only for late-summer vegetables but also for cool-season crops like spinach, radishes, kale, and lettuce as colder weather approaches.
Choosing the right weight of row cover is important. Lightweight covers offer minimal warmth but are good for keeping out insects in the spring. They allow most sunlight to reach the plants. Heavy covers provide the most warmth but block sunlight and water, which can be problematic. Medium-weight covers offer a good balance, allowing about 70% to 85% of sunlight through and warming the air by 4-6 degrees Fahrenheit. This can extend the growing season by several weeks, helping plants survive the winter and thrive in the spring.
Setting up row covers is straightforward. For low-growing plants, simply drape the fabric loosely over them and secure the edges by burying them in the soil or using stones. For taller or more delicate plants, use hoops to create a frame and drape the cover over it. Make sure to leave enough space for the plants to grow. Regardless of the setup, it's important to monitor plants regularly, checking soil moisture and ensuring that flowering plants are exposed to pollinators when needed. On warm days, remove the covers to prevent overheating, ensuring your vegetables are ready for harvest when the time comes.
