Eutrophic growth, often caused by excessive algae and organic buildup, can turn outdoor seating into an unsightly and slippery hazard. To maintain clean and safe outdoor furniture, consider these proven strategies:

1. Regular Cleaning: Frequently wash seating surfaces with a mild detergent and water to remove organic debris before algae can take hold.

2. Proper Drainage: Ensure seating areas have adequate drainage to prevent stagnant water, a prime breeding ground for algae.

3. Eco-Friendly Algaecides: Use natural solutions like vinegar or baking soda to deter algae without harming the environment.

4. Shade Management: Position seating under shade structures or trees to reduce sunlight exposure, slowing algae growth.

5. Material Selection: Opt for algae-resistant materials like treated wood, metal, or UV-stabilized plastics for long-term prevention.

By combining these methods, you can keep outdoor seating algae-free and extend its lifespan while protecting the surrounding ecosystem.
