What are the best wood preservatives for cedar outdoor flower pots in urban pollution?

Cedar is a popular choice for outdoor flower pots due to its natural resistance to decay and insects. However, urban pollution can accelerate wear and tear, making wood preservatives essential for longevity. Here are the best options:

1. Oil-Based Preservatives: Penetrate deeply, enhancing cedar's natural resistance while protecting against moisture and pollutants.

2. Water-Based Sealants: Eco-friendly and low-odor, ideal for urban settings, offering UV and pollution protection.

3. Copper-Based Solutions: Effective against fungi and insects, though they may slightly alter cedar's color.

4. Natural Oils (Linseed/Tung): Non-toxic and easy to apply, but require frequent reapplication in polluted areas.

For urban environments, choose preservatives with UV and pollution resistance to maintain your cedar pots' beauty and durability. Regular maintenance ensures long-term protection.
