Troops, let's talk about watering your turfgrass. As in mowing, I said, "High and slow." With watering, it is "Deeply and infrequently." Water composes from 75 percent to 85 percent of the weight of a healthy grass plant. It is essential for seed germination, tissue formation, plant cooling, food manufacture, and nutrient absorption and nutrient transport. A grass plant loses the most water under conditions of high light intensity, high temperature, low relative humidity, and windy conditions.
