Can polyethylene outdoor flower boxes withstand exposure to common garden fertilizers or pesticides?
Polyethylene outdoor flower boxes are popular for their durability and weather resistance, but many gardeners wonder if they can handle exposure to common garden fertilizers or pesticides. The good news is that high-quality polyethylene is chemically resistant, meaning it won’t degrade when in contact with most fertilizers or pesticides. However, prolonged exposure to harsh chemicals or improper cleaning may cause slight discoloration or surface wear over time. To maximize longevity, rinse the flower boxes after applying fertilizers or pesticides and avoid using highly acidic or abrasive products. With proper care, polyethylene planters remain a reliable choice for outdoor gardening.
