Frost blankets are coverings made of lightweight, 100% polypropylene fabric. Unlike bedsheets, burlap or painter's tarps the fabric is designed to allow plants proper airflow. Frost blankets are ultra light-weight, keeping your plants safe from damage. They are also designed to dry quickly and will not become heavy from moisture.

Frost blankets can be used for several different applications. They come in handy with newly sprouted seedlings in outdoor rows and can save your greens if used right before a frost. Bootstrap Farmer carries both a 2.5 oz. frost blanket and 4.0 oz. frost blanket.

2.5 oz.- This lightweight option is perfect for longer-term applications or in areas where only a light frost will hit. Since it is so lightweight, sunlight can still easily penetrate.

4.0 oz.- This is a heavier duty option for protection from frost. This material will not let as much light through so we suggest this is used as a temporary application. It can also be used in conjunction with the 2.5 oz for extra protection during a cold snap. This size is less ideal for long-term application as it does not allow for as much airflow or sun penetration.

Frost blankets can be installed on row crops with low-tunnel hoops or can be laid directly on the plants you are wishing to protect. The blanket can be anchored with rocks, dirt or staples.
You will want to install the frost blanket before the frost. When the sun comes out, remove the blanket and fold and store properly. If soiled, you can lightly rinse with cool water and let air dry before storing.
