What is the minimum layer of mulch required in MWELO regulations for planting areas?

MWELO, or the Model Water Efficient Landscaping Ordinance, emphasizes the importance of water conservation through effective landscaping practices. One key component in achieving water efficiency is the use of mulch, which plays a crucial role in soil moisture retention, temperature regulation, and weed suppression.

The regulations stipulate that a minimum mulch layer of 2 inches is required in planting areas. This thickness is effective at providing the needed benefits without hindering water infiltration or plant growth. A 2-inch layer is also manageable for maintenance purposes, ensuring that it is easy for landscape professionals to apply and maintain over time.

Choosing this specific depth aligns with best practices in landscape management, promoting healthy growth while minimizing the need for supplemental watering, thereby supporting the broader goals of the MWELO regulations.
