Oftentimes, I get asked, what time is the best time to irrigate a lawn. Normally, it is best to begin irrigation cycles in the early morning hours and target the water to be completed before 8 am, when the natural drying process is underway. Watering your lawn in this manner helps decrease the wet period of the turf and is a good first step in suppressing disease. Dew begins setting after sunset and dissipates in the morning as the sun rises. Dew is a combination of condensation and guttation (excretions of sap) water from the turf’s respiration. This plant exudate is full of natural juices that combine with normal condensation to create an ideal environment for disease. Planning your irrigation to help wash guttation water off the turf and interrupt the dew period is a good way to improve your lawn.
We follow these same watering principles on both courses to help reduce disease. In addition to good watering practices, you may notice our teams periodically dragging a hose down the course fairways with maintenance carts in the mornings. This process is done on days we are not mowing the fairways to remove the dew from the grass blades and promote quicker drying. Knocking the dew down not only helps keep our member’s feet dry, it also improves ball roll and aids in disease prevention. Reducing the wet period and promoting drying is an important part of interrupting the pathogen’s life cycles, minimizing disease, and promoting healthy turf. Hope to see you on the courses.
