A frost cover for plants is a simple yet effective way to shield delicate vegetation from cold damage during chilly nights. Typically made from breathable materials like fabric or plastic, it acts as an insulating barrier that traps warmth while allowing light and moisture to pass through. Gardeners use it to extend the growing season, prevent frostbite on leaves, and support plant survival during unexpected temperature drops. Easy to apply and reusable, frost covers are ideal for flowers, vegetables, and young shrubs. Using a frost cover for plants ensures better protection and healthier growth in colder climates or transitional seasons.
