Proper Watering and Fungus
Too much moisture causes disease development on turfgrass. Water logged soils do not have enough air circulation and the grass plant roots cannot absorb nutrients well. It is important to manage the amount of water on your lawn from both natural rainfall and additional watering to avoid diseases. Deep, infrequent watering to avoid drought stress is best. Watering deeply two or three times a week in the morning, for 30-45 minutes when necessary,will encourage deep root growth. Drought stressed turf lacks vigor and is prone to disease. Watering early in the morning to allow leaf blades to dry is best. Do not water after 4pm. At this time of day, the soil is at it's hottest but the air temperature is beginning to cool. Water will not evaporate well at this time and will encourage fungal growth. Selective pruning of trees and shrubs helps sunlight reach the grass areas and increases air circulation.
