As temperatures drop, your urban planter boxes need special attention to survive the winter months. Start by removing annual plants and composting healthy foliage. For perennial plants, apply a thick layer of mulch—such as straw or wood chips—around the base to insulate roots from freezing temperatures.
If your containers are movable, relocate them to a sheltered spot against a south-facing wall or under an overhang. For fixed planters, wrap them in bubble wrap or burlap to provide extra insulation. Ensure proper drainage by checking that drainage holes remain clear; saturated soil can freeze and damage root systems.
Consider planting cold-hardy varieties like ornamental kale, winter pansies, or evergreen herbs that can withstand frost. For empty containers, clean and store them upside down to prevent water accumulation.
In regions with severe winters, create a protective cover using frost cloth when temperatures plummet below freezing. Remember to water occasionally during dry winter spells, as plants can dehydrate in cold winds. These simple steps will help your urban garden thrive when spring returns.
