What are the best methods to prevent algae growth on synthetic rattan flower boxes?

Algae growth on synthetic rattan flower boxes can be unsightly and difficult to remove. Fortunately, there are several effective methods to prevent it. First, ensure proper drainage to avoid water accumulation, as stagnant water promotes algae. Regularly clean the boxes with a mild soap solution or a vinegar-water mix to remove dirt and spores. Applying a UV-resistant sealant can also deter algae by creating a protective barrier. Additionally, placing the boxes in areas with good airflow and partial sunlight reduces moisture buildup. For long-term prevention, consider using algae-resistant synthetic rattan materials. These simple steps will help keep your flower boxes looking fresh and algae-free.
