What disease is commonly spread by overwatering and poor drainage in lawns?

Brown patch disease is commonly spread by overwatering and poor drainage in lawns. This fungal disease thrives in conditions where excessive moisture is present, particularly in warm, humid environments. When lawns are overwatered or if there is poor drainage, the soil remains consistently wet, creating an ideal environment for the pathogens responsible for brown patch disease to flourish. The wet conditions not only promote the growth of the fungus but also weaken the grass blades, making them more susceptible to infection.

This disease typically manifests as circular brown patches in the lawn, and it can spread rapidly if environmental conditions persist, leading to widespread damage. Management practices for brown patch include improving drainage, adjusting watering schedules to avoid excess moisture, and ensuring proper lawn maintenance through aeration and appropriate fertilization. Understanding the relationship between water management and the prevention of this disease is crucial for maintaining a healthy lawn.
