Whether you can leave your urban planter boxes outside during winter depends on several key factors. First, consider the plants themselves. True perennials and cold-hardy annuals like ornamental kale may survive, while tropicals will not. Second, the container material matters. Terracotta and ceramic can crack in freeze-thaw cycles, whereas wood, fiberglass, and thick plastic are more resilient. To improve chances of survival, insulate the roots by wrapping the planter in burlap or bubble wrap, move it to a sheltered spot against a building wall, and ensure excellent drainage to prevent soil from becoming waterlogged ice. For non-hardy plants, bringing the planter indoors to a cool, bright space like a garage or basement is the safest option. Ultimately, successful overwintering blends selecting the right plants, protecting the container, and understanding your local climate's specific challenges.
Is it okay to leave my urban planter boxes outside during the winter, or should I bring them in?
