What is a recommended cultural practice to avoid severe thinning caused by turf diseases?

Maintaining adequate soil nutrients is fundamental in preventing severe thinning caused by turf diseases. Healthy, well-nourished turfgrass possesses greater vigor, resilience, and resistance to pests and diseases. Proper nutrient management ensures that the grass can efficiently utilize available resources, enhancing its overall health and capacity to recover from stressors, including diseases.

Fertilization practices that promote balanced nutrient levels—including nitrogen, phosphorus, and potassium—encourage robust root development and improve the plant's ability to withstand adverse conditions. This, in turn, helps maintain denser turf, reducing the likelihood of disease establishment and spread.

In contrast, practices like over-fertilizing can lead to excessive growth that weakens grass health over time, while mowing too low can stress the grass and make it more susceptible to diseases. Furthermore, frequent watering without regard for proper moisture levels can lead to waterlogged conditions, promoting disease risk. The focus on maintaining adequate soil nutrients provides a sound basis for establishing a strong, disease-resistant turf.
