Stormwater management
Water quality
Older, established green roof plant communities are more likely to absorb nutrients from rainfall and media than younger communities. Green roofs can act as either sources of nutrient runoff or sinks. Low to medium dosages of controlled release fertilizers, use of species that require little to no fertilization, using less nutrient-rich organic matter amendments, and reducing irrigation will improve a green roof’s stormwater management capabilities.
