your grass for telltale signs of wilting, like irregular patches (bluishgreen to purple) during the hot part of the day, and “footprinting” when you walk across your lawn. If you can, avoid late afternoon or evening irrigation. Grass that stays wet for a long time favors development of diseases. However, don’t avoid watering in the late afternoon if this is the only time you can water. Avoiding late afternoon is secondary to providing needed water.
Where rainfall is very limited in the summer, and where heavy clay soils prevent watering to the full amount at one time, more frequent watering is necessary.
How to water. The key to watering your lawn is to get enough water into the soil to thoroughly soak the root zone. How can you determine if you are getting the right amount of water on your lawn? The weekly requirement may be as much as lVz inches during hot, dry summer weather.
Some basic guidelines:
— measure the amount of water you apply by placing a can under the spray of the water from your sprinkler or irrigation system. If you are watering once a week, you should water long enough to fill the can to a depth of 1 to IV2 inches.
Alternatively, check with your lawn specialist. Remember, if you are watering daily, you are encouraging weeds and causing the decline of your lawn.
