Frost Protection

Frost cloth for plants, frost blankets, floating row covers, protective bags, hoops, and fastening supplies can help reduce crop exposure to cold air during sudden temperature drops. Match the cover to the crop, expected low temperature, fabric weight, light transmission, and whether it will rest loosely on plants or be supported above them.

Choosing frost cloth and plant covers

  • Lightweight fabric: admits more light and may suit mild conditions or insect exclusion when the product is rated for that use.
  • Medium- and heavyweight fabric: provides more insulation but admits less light.
  • Plant bags and blankets: simplify coverage for individual plants, containers, and small beds.
  • Hoops, clips, and clamps: support material and help secure the perimeter.

Install covers before temperatures fall, extend material to the ground, and secure the edges. Avoid compressing delicate foliage, and remove or vent covers as conditions and product directions require. Protection varies by material, installation, wind, soil heat, and duration of cold.
