Frost Blankets are common practice in colder climates and frequently used to cover frost-sensitive plants. During the day, soil collects heat, whilst overnight soil loses heat. Covers trap the warmth of the soil, keeping warmer air down close around the plant, thus preventing the rapid surface cooling conducive to frost formation. Additionally the frost blanket, becomes the surface on which the moisture freezes rather than the plant.

They are light enough to be laid on top of plants, but also effective over hoops or trellis. Ensure the frost blanket is securely anchored and sealed where it meets the ground to prevent breezes from removing the cloth. It is not harmful to plants if it remains on for extended periods of time as it will provide a warm, light-filled and sheltered micro-climate for sensitive plants to flourish. Available in two sizes.
