Rain gardens have limitations in fully purifying pollutants due to their weak internal degradation process. When positioned near roads, they can accumulate nutrients, heavy metals, and organic pollutants from runoff, diminishing their effectiveness in pollution mitigation.
These negative effects highlight the importance of regular maintenance, proper siting, and consideration of alternative methods for managing polluted runoff. To address these challenges, monitoring and managing the accumulation of pollutants in rain gardens is essential. Incorporating diverse plant species can enhance pollutant uptake and degradation. Regular soil testing can help detect and address nutrient accumulation. Furthermore, ensuring proper drainage design can prevent overflow and subsequent pollution.
Due to their weak internal natural degradation, rain gardens cannot achieve complete purification of pollutants20. Rain gardens that are arranged around roads and receive runoff with a high degree of pollution often accumulate nutrients, heavy metals, and organic pollutants21,22.
How much water can a rain garden hold?
A rain garden can hold more water by watering slowly and deeply less frequently, rather than watering lightly more often, to promote plant growth.

What is one plant that is indigenous?
One indigenous plant is the butterfly milkweed. When creating a rain garden, ensure it can hold at least an inch of rain to capture the initial runoff with pollutants. If the garden is on a vegetated surface like a slope that promotes percolation, it can be smaller compared to the area collecting the water.
What are the enemies of lantana?
Lantanas’ enemies include frost, which can kill them. In warm regions, lantanas thrive as tender perennials and commonly survive for two to five years. With proper care, they can even live for up to a decade. Other threats to lantanas include diseases, pests like spider mites and whiteflies, and competition from invasive species. Proactive pest management and providing optimal growing conditions can help protect lantanas from these enemies and promote their longevity.
Why are lantana dying?
Lantanas may be dying due to powdery mildew from too much shade, root rot from poor drainage or frequent watering, and reduced flowering from excessive fertilization leading to disease susceptibility. Ensure proper sunlight, well-drained soil, and balanced fertilization to maintain lantana health. Regularly monitor for signs of powdery mildew and adjust care accordingly to prevent plant decline.
What can I replace shrubs with?
