Prof. Samuel Fitzgerald, Ph.D.The best way to curb lawn problems is through proactive practices that prevent issues before they arise. For many years, I have established healthy turf by being proactive and preventing problems rather than reacting to them. A few core strategies include timing pre-emergent applications properly, aerating the lawn annually, and mowing it to the proper height; this creates an environment that is unwelcoming to weeds and pests.
Pre-Emergent Timing
- Apply when soil reaches 55°F for crabgrass prevention
- Use corn gluten meal for organic pre-emergent
- Reapply after heavy rains washing away protection
Aeration Benefits
- Relieve compaction allowing water and oxygen penetration
- Improve root growth reducing stress vulnerability
- Enhance microbial activity for natural disease resistance
It is essential to maintain your grass at the proper mowing height for the specific type of grass. Taller grass blades shade the soil, preventing weed seed germination and reducing evaporation, which would otherwise cause the soil to dry out. Never mow more than one-third of the total blade length to avoid stress. In the summer, I keep my cool-season grass at 3.5 inches tall, which shades the soil and provides about a 90% block against any weed seeds that land in the soil.
Test your soil for nutrient imbalances every two or three years before problems appear. If you detect that the pH of your soil is not where it should be, consider applying lime or sulfur to adjust it. Also, check regularly for signs of early problems, such as discoloration or thinning of the skin. In my experience, regular inspections enable me to identify nutrient deficiencies early, minimizing the potential for significant problems later on.
Implement cultural controls regularly. Water deeply but infrequently to encourage the growth of deep roots. Remove any thatch that exceeds one-half inch. Furthermore, overseed every year to maintain thick turf year-round. Thus, cultural control practices enhance the resilience of your lawn, reducing the potential for intervention over time.
Providing proactive care ultimately saves time and money. You can start by conducting a soil test, followed by proper mowing techniques. Your lawn will naturally become more resistant to common issues, and consistent prevention yields sustainable and beautiful turf year after year.
