DIY Frost Covers for Zone 5: How to Make Your Own

by

Protecting your garden plants during harsh winter months is essential, especially in Zone 5 where cold temperatures can cause damage. Making your own frost covers is an affordable and effective way to extend your growing season and safeguard your plants from frost and freezing temperatures.

Why Use DIY Frost Covers in Zone 5?

Zone 5 experiences winter lows typically between -20°F and -10°F. Frost covers help trap heat and moisture, creating a microclimate that shields plants from frostbite. Homemade covers are customizable, cost-effective, and environmentally friendly compared to commercial options.

Materials Needed

  • Clear plastic sheeting (6-10 mil thickness)
  • PVC pipes or metal stakes
  • Duct tape or zip ties
  • Scissors
  • Rope or twine
  • Optional: Row covers or fabric for additional insulation

Step-by-Step Instructions

Step 1: Choose a location in your garden that offers some natural protection from wind. Clear the area of debris and weeds.

Step 2: Measure the length and width of the area you want to cover. Cut the plastic sheeting accordingly, leaving extra at the edges for securing.

Step 3: Install the support structure by inserting PVC pipes or stakes into the ground along the length of the area. Space them about 2-3 feet apart for stability.

Step 4: Drape the plastic sheeting over the support structure. Secure the edges to the ground using rocks, soil, or stakes to prevent wind from lifting the cover.

Step 5: Use duct tape or zip ties to attach the plastic to the supports, ensuring a tight fit to trap heat inside.

Step 6: For extra insulation, you can add a layer of row cover or fabric over the plastic, especially during extremely cold nights.

Additional Tips for Success

  • Check weather forecasts and cover plants before temperatures drop below freezing.
  • Remove the covers during the day to allow sunlight and air circulation.
  • Secure the edges well to prevent wind damage.
  • Use breathable materials if possible to prevent condensation buildup.

Conclusion

Creating your own frost covers for Zone 5 gardens is an easy and economical way to protect your plants during winter. With simple materials and some DIY effort, you can extend your growing season and ensure healthy plants come spring.
