Are there fungal degradation risks for polyethylene planters in humid climates?
Polyethylene planters are popular for their durability and resistance to weathering, but in humid climates, concerns about fungal degradation may arise. While polyethylene is generally resistant to microbial attacks, prolonged exposure to moisture and organic matter can create conditions where mold or mildew may grow on the surface. However, this growth typically doesn’t compromise the structural integrity of the planter. To minimize fungal buildup, regular cleaning and proper drainage are recommended. High-quality polyethylene planters with UV stabilizers also tend to resist discoloration and surface degradation better. For gardeners in humid regions, choosing thick, non-porous polyethylene and ensuring adequate airflow around planters can further reduce risks.
