Plant Protection Frost Blankets help protect delicate plants and fruit from harsh weather.
Even though I live in relatively temperate Northern California, it does get cold enough during some nights each year to damage or kill tender plants and citrus. I just covered my lemon tree, some papaya plants, and a pineapple plant with frost blankets so I don't get caught by surprise. Actually, I don't have much hope for papaya and pineapple because they are tropical and I am growing those on a lark.
The Frost Blankets are designed for plant beds, vegetable gardens, fruiting trees, and shrubs. They are 12 feet by 10.5 feet (3.66 m x 3.2m). They help to reduce damage from frost, wind, and winter burn. They allow light, air and moisture to pass through the fabric. Unlike covering your plants with ugly blue tarps, this blanket don't amplify the rain if the plants are near your bedroom window.
The fabric is lightweight and durable. This is the third year that I am reusing some of my frost blankets. You can anchor the blanket to the ground with a type of pins similar to those used for holding down drip irrigation pipes. I typically wrap my plants with the blanket and secure it with multiple clothes pins.
You might want to check with your local nursery to confirm that these are suitable for any plants which you might want to cover.
