Frost Cloth and Blanket Supplies
It’s not always possible to bring your plants in from the cold, but you can bring warmth to them. Frost cloths protect your plants and garden from winter cold and overnight freezes by creating a more stable environment around them. Our selection of row covers, garden fleeces, and plant protection fabrics helps safely carry plants through the coldest months while still allowing air, light, and moisture to pass through.
Frost Cloth and Cover Materials, Features and How They Work
Most frost blankets are made from UV-stabilized polypropylene or fabric blends, offering a balance of durability, lightweight protection, and breathability. They work by trapping radiant heat from the soil, creating a warmer microclimate that protects plants from freezing temperatures.
Additional benefits include:
- Allows air, rain, and irrigation to pass through
- Helps prevent plant burn and wind damage
- Can reduce insect exposure and soil erosion
- Supports season extension into colder months
Frost Blanket Weights and Temperature Protection
Frost covers vary by thickness (oz/yd²), which determines their level of protection:
- Lightweight (0.5–1.0 oz): ~2–6°F protection
- Medium (1.0–1.5 oz): ~4–8°F protection
- Heavyweight (1.5+ oz): 8–10°F+ protection
Heavier frost covering fabrics provide more insulation, and layering multiple covers can further increase protection during extreme cold.
Affordable Frost Protection for Plants
Each frost cover is designed to keep cold air out while still letting moisture and air in so your garden can flourish. Choose from fabric and polypropylene materials that are built for extended use. Most products are available in multiple sizes, with bulk discount pricing for commercial growers, home gardener, and serious hobbyists.
