What are the risks of using unsealed concrete outdoor planters in humid climates?
Using unsealed concrete outdoor planters in humid climates can lead to several risks. First, prolonged exposure to moisture causes concrete to absorb water, leading to cracks and structural weakening over time. Second, humidity encourages mold and mildew growth, which can harm plants and create unsightly stains. Third, freeze-thaw cycles in colder humid regions exacerbate cracking, further damaging the planter. Additionally, salt and mineral deposits may form on the surface, degrading its appearance. To prevent these issues, sealing concrete planters with a waterproof sealant and ensuring proper drainage are essential steps for longevity and plant health.
