Lawn Disease and How to Prevent It

Maintaining a healthy lawn is the best way to avoid disease outbreak in turf grass. Your lawn requires optimal amounts of water and fertilizer, aerated, well-drained soil, and the right mowing system. If these factors are missing or in excess, the grass can become stressed and more susceptible to disease. Selecting a grass species that is adapted to the local climate and following through with proper maintenance are steps that can be taken to avoid severe lawn disease.

Many common diseases are active under specific environmental conditions that affect the lawn for a short time. When the weather is more favorable, the lawn will often recover so long as cultural practices are followed. If conditions and practices that favor disease continue, it can result in long-term damage to your lawn, and that can be difficult to recover from.

If you have a lawn that’s suffering from injury, identifying the cause will help you know how best to treat it. This can be difficult as diseases aren’t always the primary reason. Diseases typically start off as small patches or spots of drying grass that spread over time. If this damage is sudden and widespread, it’s possible pests or insects, weeds or too much or too little water or fertilizer can be contributing to the problem. Your grass could be damaged from dog urine, herbicides or other chemicals, poor drainage, competing for vegetation or thatch.

Nearly all lawn diseases result from pathogenic fungi that infect blades, stems, or roots of the grass. These diseases have identifying symptoms, usually including leaf spots, white, powdery growth, thin, open grass, and small to vast areas of discolored or dying lawn. Rotted crowns and roots, yellow leaves, stunting and wilting are other signs of affected lawn areas.

The most common causes of discolored lawns are from irrigation problems. Ensuring even water coverage, and that the grass isn’t getting too much or too little water is key.

To prevent lawn diseases, use cultural practices to promote your grass to grow with a good recuperative ability. Irrigation, fertilization, mowing, soil cultivation, and thatch removal are good cultural practices to do to help prevent diseases.
