Frost blankets create a protective layer between your plants and cold, drying air. Most are made of breathable, non-woven fabric, so they help buffer chilly temps while still allowing light, air, and some moisture to reach the plant.

• Cold protection: Helps reduce damage during light frost and sudden cold snaps.
• Breathable design: Ventilates to minimize condensation and let plants keep growing.
• Different styles: Floating row covers for beds and jackets with drawstrings or zippers for shrubs.
• Season extension: Can support earlier planting or later harvests.

Effectiveness can vary based on weather, plant type, and how well the cover is secured.

If you’re not using a traditional frost blanket, there are other plant covers that offer similar protection.

• Floating row covers: Lightweight garden fabric that drapes over beds or rows.
• Burlap wraps: Help shield tree trunks and shrubs from wind and cold.
• Pop-up plant covers: Tent-style enclosures that add a quick, portable barrier.
• Insulated raised bed covers: Panels or liners that add warmth to boxed beds.

Choose breathable options when possible and secure edges with clips, ties, or stakes. If using clear enclosures, consider venting on sunny days to avoid overheating. Results can vary with local conditions.

Timing depends on the weather and the type of cover. For short cold snaps, many gardeners place the frost blanket before evening and remove or vent it the next morning once temps rise.

• Overnight frost: Cover in the evening; remove or open when it warms.
• Extended cold: Lightweight floating row covers can stay on for days or longer, as they allow light and moisture through.
• Shrub jackets: Loosen drawstrings or unzip on mild days to prevent heat buildup.

Check soil moisture and plant condition regularly. Adjust based on local forecasts and plant needs.

Frost blankets are used to help shield plants from cold, wind, and light frost while allowing air and light to pass through.

• Cold protection: Offers a buffer during chilly nights and cold snaps.
• Wind and sun moderation: Helps reduce stress from harsh wind or strong sun.
• Pest and bird barrier: Some fabrics deter insects and birds.
• Seedling support: Can aid germination and early growth by creating a milder microclimate.

They’re available as floating row covers for beds and jackets or bags for shrubs and small trees. Benefits can vary by plant and weather patterns.

Start by measuring the area you want to cover and add extra for draping and securing.

• For beds and rows: Choose a sheet that covers the full bed plus a margin to anchor along the edges.
• For shrubs/trees: Jackets or bag-style covers should fit the plant’s height and canopy, with room for drawstrings or zippers.
• Fabric weight: Lighter cloth allows more light; heavier options add warmth but reduce light.
• Securing: Plan for stakes, clips, or ties to keep it in place.
