Frost blankets are protective covers made from lightweight materials that help shield plants from cold temperatures and frost. They work by trapping heat close to the ground, creating a warmer microclimate for the plants underneath. These blankets are especially useful in gardens and farms during late spring or early fall when temperatures can drop unexpectedly. Typically, frost blankets are easy to use and can be placed directly over plants or garden beds. They come in various sizes and thicknesses, allowing gardeners to choose the right type for their specific needs. Using frost blankets can help prevent damage to delicate plants, ensuring a healthier garden.
