Know before you buy
The 1.5 oz. fabric is designed to create a warmer microclimate around your plants, typically providing several degrees of protection against frost and light freezes. While it helps shield plants from cold snaps, it is not intended to prevent damage during extreme, prolonged deep-freeze conditions.
Yes, the material is porous, which allows sunlight, air, and water to reach your plants. You can leave it in place for extended periods to protect against fluctuating temperatures without needing to remove it daily.
At 1.5 oz. per square yard, the fabric is lightweight enough to be draped directly over most plants. However, if you are protecting delicate stems or tall vegetables, using support hoops or stakes can prevent the fabric from crushing the foliage.
Because the fabric is lightweight, you should secure the edges to the ground using landscape staples, heavy stones, or bricks. Ensure the edges are sealed well to trap the heat generated by the soil beneath the blanket.
Yes, the woven polypropylene material is easy to cut with a standard pair of heavy-duty scissors. You can trim the 6-foot wide rolls to fit your specific row lengths or plant groupings without the fabric fraying excessively.
