Are cast iron outdoor tree boxes more susceptible to damage in freezing climates?
Cast iron outdoor tree boxes are known for their durability, but their performance in freezing climates raises concerns. When temperatures drop, cast iron can become brittle, increasing the risk of cracking or breaking under stress. Additionally, moisture trapped in the soil can expand when frozen, exerting pressure on the box walls. To mitigate damage, consider using insulated liners, proper drainage, or relocating vulnerable boxes during extreme cold. While cast iron is robust, proactive winter care ensures longevity in harsh climates.
