How do canvas outdoor planters compare to polyester in terms of resistance to fading from air pollution?

When choosing outdoor planters, resistance to fading from air pollution is a key factor. Canvas and polyester are popular materials, but they differ in durability. Canvas planters, made from natural fibers, tend to absorb pollutants more easily, leading to faster fading over time. Polyester, a synthetic material, is more resistant to chemical reactions caused by air pollution, retaining its color longer. Additionally, polyester often includes UV-resistant coatings, further enhancing its fade resistance. For urban environments with high pollution levels, polyester planters generally outperform canvas in maintaining vibrancy. However, canvas offers a more organic aesthetic, which some gardeners prefer despite its shorter lifespan in polluted areas. Regular maintenance, like cleaning and protective sprays, can help extend the life of both materials.
