As temperatures drop, preparing your urban planter boxes is crucial for protecting your plants and soil. Start by removing any dead or frost-sensitive annuals. For perennial plants, research their hardiness; some may survive in large, insulated containers, while others need moving to a sheltered spot. Improve drainage by ensuring all pots have unobstructed holes to prevent waterlogging and root rot from frozen soil. A key step is to insulate the containers themselves. Wrap boxes with bubble wrap, burlap, or horticultural fleece to shield roots from freezing temperatures. Apply a thick layer of mulch, like straw or wood chips, on the soil surface to regulate temperature and retain moisture. Reduce watering significantly, as plants enter dormancy and excess moisture is a greater threat than cold. Finally, consider consolidating smaller pots into a protected area or against a building wall for added warmth. With these steps, your urban garden will be better prepared to thrive again come spring.
