It's best to use less fertilizer rather than too much, because overfertilizing burns grass. Apply the fertilizer to dry grass and water it into the soil. Never apply more then 2 pounds of nitrogen per 1,000 square feet to the lawn at one time. Use chelated iron and zinc in spring and fall to promote a healthier lawn. Use according to label directions.
Turf irrigation is critical for healthy grass.
Deep watering is the best way to apply water. This promotes deeper roots, which are not as susceptible to drought as shallow root systems. Light, frequent waterings will encourage short roots that are prone to drying out rapidly, particularly when temperatures exceed 80 degrees Fahrenheit. When plants become stressed they also become susceptible to disease. It is important to find out how much water the sprinkler applies in an hour.
