Can the fabric covers protect plants during the winter?
Frost Protek® fabric covers are designed for use during the growing season, or as long as there is live foliage on the plant. They can be used for periodic frost protection in climates with a year-round growing season, such as Florida and California. In most climates, perennials do not need protection from the elements while they are dormant. Be sure to remove covers once foliage has died back to ensure bare branches don't puncture your covers. You can use them again in the new growing season once foliage starts to form to insulate young leaves from a frost or cool nights.

What is the fabric?
The weather protection fabric is 100% polypropylene, which is the same fabric used by commercial growers for frost and pest protection. The fabric is lightweight and doesn't crush plants. It is breathable and enables the plant to receive the air it needs. Light penetrates through the fabric to the plants. The fabric weight is 0.9 oz. per square yard (metric 30 grams per square meter). This weight protects from 4° to 6° below freezing, or about 28° to 26° Fahrenheit (-3.0° Celsius).
Can the covers be washed?
Yes. The cover may be washed in cold water. It air dries quickly. DO NOT dry it with heat. DO NOT iron the cover.
How long will the covers last?
With normal use and care, the cover should last for several seasons. It is lightweight and folds small to store easily. Store out of direct sunlight or UV light to prolong the life of the fabric.
How can I secure the garden bed or row cover in place?
When wound around a plant or display, the cover may be held in place with clothes pins, safety pins, or other similar items. The cover may be fastened to itself or to the container. When used for in-ground plants, it may be held down with any type of heavy object such as a rock, brick, dirt, or landscape fabric pin. For raised beds, a clamp works well.
