Plant Covers

Frost covers (frost blankets) trap heat radiating from the soil and create a buffer of warmer air around the plant, raising the temperature underneath by several degrees, enough to protect against light frost. They also block frost from settling directly on foliage. The fabric breathes and lets light and water through, so it can stay on through a cold spell.

Frost blankets (row cover fabric) breathe, transmit light, and can stay on plants for extended protection without overheating or trapping moisture. Plastic traps heat fast but must be vented and removed promptly, and it can damage foliage it touches in freezing conditions. For most frost protection, breathable fabric is safer and more forgiving than plastic.

Frost covers typically raise the temperature underneath by several degrees, with heavier fabrics offering more protection than lighter ones. This protects against light to moderate frost but not a hard, deep freeze. Match the cover weight to the expected cold: lighter for light frost, heavier for harder freezes, layering for extreme cold.

Apply covers before the cold arrives, in the evening before a frosty night, securing the edges so heat does not escape and wind does not lift them. Breathable fabric can stay on through a cold spell, but remove or vent covers once temperatures rise to avoid overheating on sunny days, especially with any plastic.

Anchor the edges with stakes, pins, weights, or soil so wind cannot lift the cover and let the trapped warm air escape, which defeats the protection. On exposed sites, secure thoroughly. Covers that blow off in the night leave plants unprotected exactly when they need it, so anchoring is as important as the cover itself.

Yes. Frost blankets, row covers, and plant protection materials are stocked in rolls and bulk quantities with volume pricing by quote. Growers and operations protecting plantings through cold seasons benefit from ordering in volume ahead of frost, matched to the coverage area and the protection level their crops need.
