Proper Fertilization & Lawn Care
- Excess nitrogen in your soil from too much nitrogen fertilizer can increase the disease potential for brown patch.
- Apply nitrogen fertilizers at a low rate throughout the growing season as needed, careful to avoid applying during the warm, humid weather that brown patch thrives in.
- Avoiding over fertilization will help to reduce the likelihood that you will have a brown patch problem in the summer.
*You may need to collect a soil sample for soil testing to determine your lawn's nitrogen level.
Follow Proper Lawn Care Practices
Reducing the amount of water that is in contact with the soil/foliage is an important step in preventing brown patch as well as a host of other fungal diseases, since the damp conditions are perfect for fungal growth.
- Water lawn only as necessary, aiming to irrigate in the very early morning hours to give the water more time to evaporate off your grass.
- Ensure your soil has the best drainage as possible.
- Increase sunlight and air circulation by removing thick, unnecessary foliage, trimming bushes and trees properly, etc.
