Outdoor plant boxes are a great way to bring greenery into urban spaces, but they often face challenges from air pollution. To ensure your plants thrive, follow these steps to create a pollution protection plan:

1. Choose Pollution-Resistant Plants: Opt for species like spider plants, peace lilies, or ferns, which are known to tolerate polluted environments.

2. Use Protective Barriers: Install mesh screens or lightweight covers to reduce direct exposure to pollutants like dust and smog.

3. Regular Cleaning: Wipe leaves with a damp cloth weekly to remove dust and chemical residues that can block sunlight and hinder photosynthesis.

4. Water Wisely: Use filtered or rainwater to avoid contaminants found in tap water, and ensure proper drainage to prevent toxin buildup in soil.

5. Soil Health: Add activated charcoal or organic compost to the soil to neutralize pollutants and improve nutrient absorption.

6. Monitor Air Quality: Place air quality sensors near your plant boxes to track pollution levels and adjust care routines accordingly.

By implementing these strategies, your outdoor plant boxes can stay healthy and vibrant, even in polluted urban settings.
