Establishing Deeper Roots
Lawns with deep root systems are healthier and use less water. Avoid light frequent watering on established lawns. Applying water in less frequent waterings allows water to soak deeply into soils. This will allow roots to use water in the ground rather than only surface water, making your lawn more drought tolerant.
“Cycle and Soak.” This method allows water to soak deep into your soil. This works by dividing the current run time into three separate cycles (For example, if you are currently watering in 21-minute watering cycles, water instead in three seven minute cycles. Once you have completed the first seven-minute cycle, run a second and third cycle.) This will allow an air pocket to form between the three layers of water, pushing the water deeper into the soil.
Water usage averages are affected by many variables. Water usage may need to be increased due to poor soil, wind, excessively high temperatures, reflective surfaces (sod near fences, brick walls, etc.), or in areas where run-off may occur (e.g., slopes, hills). Additionally, water usage may need to be decreased in shady areas.

 
 
Mowing
Is your lawn shorter than your carpet? Mowing your lawn at such a short length hurts the grass, wastes water and encourages more green waste.
By raising your lawn mower height another 1⁄2 to 1 inch, you are promoting the conservation of water in grass. Grass will shade itself as it grows longer, reducing its overall water need. This, in turn, reduces the growth rate of the grass- meaning less frequent mowing! Experts recommend cutting grass to a total length of 3 inches, and removing no more than one-third of the leaf blade per mowing.
 
  Stressing
Ever heard the expression "What doesn’t kill you only makes you stronger"? In order to make your grass heartier, try stressing it out! By going an extra day without water here and there, you are promoting deeper root growth. The deeper the roots are allowed to penetrate the soil, the better overall health of your lawn. Roots will only grow as far as they need to in order to get water. If you are always giving them water up near the surface of the lawn, the plants have no incentive to grow deeper. You can easily check your rooting depth by using a soil probe or screwdriver.
Try waiting as long as possible in the spring to water your grass. The longer you wait, the healthier your lawn will be in the summer months. And don’t worry it’s virtually impossible to kill your lawn. The lawn may turn brown in areas, but it is just the plant going DORMANT, not dying. Adding water will make that spot spring back to life!
