Which practice is recommended to maintain turf health and prevent disease development?

• A. Select appropriate turfgrass species and varieties
• B. Over-fertilize to accelerate growth
• C. Increase compaction to support the roots
• D. Mow as low as possible at all times

Answer: (A)

Choosing turfgrass species and varieties that fit the site is the best way to keep turf healthy and reduce disease pressure. When the grass is well-suited to the local climate, soil, and wear, it establishes a strong, dense stand that tolerates stress and recovers quickly, leaving fewer openings for pathogens to take hold. Many adapted cultivars also have resistance to common diseases, so you’re starting with a plant that’s naturally better prepared to stay healthy under typical conditions. Other practices tend to stress the turf and create environments where diseases can develop more easily. Over-fertilizing can produce lush, soft growth that is more prone to disease and creates thatch and poor air movement. Increasing soil compaction limits root growth and reduces drainage and airflow, which keeps moisture around roots and favors pathogens. Mowing too low damages leaf tissue, weakens roots, and stresses the plant, making it more susceptible to disease and weed invasion. By aligning the grass choice with the environment, you set up the turf to resist disease and thrive with less chemical intervention.
