What are the best fabrics for insulating outdoor flower boxes in winter?
When winter arrives, protecting outdoor flower boxes from freezing temperatures is crucial to keep plants healthy. The best insulating fabrics for this purpose include burlap, fleece, and horticultural frost cloth. Burlap is breathable and durable, allowing air circulation while shielding plants from frost. Fleece provides excellent insulation, trapping heat without suffocating plants. Horticultural frost cloth is lightweight yet effective, blocking cold winds while letting sunlight through. Avoid non-breathable materials like plastic, as they can cause condensation and mold. For added protection, layer fabrics or combine them with mulch. Choosing the right fabric ensures your flower boxes stay insulated, helping plants survive harsh winter conditions.
