Disease problems are minimized by good lawn care. Most diseases attack only weak grasses. Healthy turf will withstand infestation and recover faster than neglected turf. Good care practices include:
Use enough fertilizer to keep grass growing vigorously, but avoid too much fertilizer which produces unhealthy grass.
Mow when the grass becomes one third taller than the desired height. Remove no more than one inch at any one time.
Keep your mower blades sharp.
