👉 Strewage is a type of water waste that is commonly used in landscaping or gardening to control weeds and maintain soil moisture. It is typically made up of small, fine particles such as sand, gravel, or other materials that are thrown down from a hose nozzle onto the lawn or garden bed. The purpose of strewage is to help prevent the growth of weeds by covering them, which helps to reduce soil erosion and improve soil structure.
