Prof. Martin Thorne, Ph.D.Suppose frost is imminent in your garden, and there is no specialized frost cloth material available. In that case, you may be able to use items you have at home for temporary protection. While these items offer only limited protection, it is better than having no protection at all. Be aware of these limitations if you intend to use them to help keep plants alive.
Common household substitutes include bed sheets, burlap, and cardboard boxes. Each has its own relevant advantages and disadvantages. This will depend on the materials you have available and the conditions you are likely to face. While none are ideal, they can provide some protection from frost in an emergency.
Bedsheets
- Provide 1-3°F temperature increase
- Become waterlogged and heavy when wet
- Block 30-50% light transmission
- Single-use typically due to moisture damage
Burlap
- Offers moderate 2-4°F insulation
- Rots quickly when exposed to moisture
- Allows 40-60% light penetration
- Lasts only one season maximum
Cardboard Boxes
- Traps heat effectively during dry cold
- Blocks 100% light preventing photosynthesis
- Becomes ineffective when wet
- Works only for low-growing plants
Correct application practices maximize household substitutes. Use bed sheets loosely draped on the plant with the edges secured by rocks. Wrap burlap loosely around the shrubs, avoiding any materials that might tighten it. Place cardboard boxes in the afternoon or before sunset and remove them at dawn. These methods help to limit new damage that may be incurred.
Moisture control is significant when using home materials. As soon as overdrapes are removed from frost-threatened shrubbery, they should not be left on plants while dampened in any way. Drying sheets or burlap left on plants can cause mildew or fungus, which can also damage the plant itself. The placement of these protective measures is intended to allow time for durable frost threat protective covers to be applied when no moisture is present.
Invest in high-quality frost protection fabric to ensure a reliable cover for your plants. Household alternatives, such as blankets, sheets, and tarps are okay for one-night emergencies, but not for extended cold weather. Provide your garden with consistent, professional-grade frost protection against freezing temperatures.
