Which cultural management practice would help reduce weed problems in turf?

Watering infrequently and deeply is an effective cultural management practice for reducing weed problems in turf. This method encourages the development of a deep and extensive root system in turfgrass. When grass plants are able to establish strong, deep roots, they become more competitive against weeds that typically have shallower roots. This competition for nutrients, water, and light helps to suppress weed growth.

Additionally, infrequent and deep watering promotes soil health by encouraging deep drainage and minimizing surface moisture, which can create ideal conditions for weed seeds to germinate. In contrast, frequent shallow watering can lead to weak turfgrass and provide ideal conditions for many weed species to thrive, as they often require less water to germinate and establish themselves.

Implementing this watering strategy significantly contributes to a healthier, more resilient turf ecosystem, making it less susceptible to weed invasion.
