What is the duration for which temporary seed and mulch can be applied?

Temporary seed and mulch are essential components in erosion and sediment control practices, especially during the establishment phase of vegetation on disturbed soils. The maximum duration for which temporary seed and mulch can be applied is six months. This period allows sufficient time for the temporary vegetation to germinate, establish, and provide adequate soil coverage to prevent erosion, thus serving its purpose effectively.

After six months, if the desired vegetation is not established, the condition of the site may require re-evaluation and possible reseeding or alternative erosion control measures. This timeframe aligns with best management practices that dictate timely maintenance and monitoring of erosion control practices to ensure soil stability and prevent sediment runoff.

In contrast, durations longer than six months could lead to issues such as the temporary vegetation dying off or becoming ineffective, and could complicate site maintenance efforts. Therefore, recognizing the six-month timeframe is crucial for effective erosion and sediment control strategies.
