The overall goal in watering the plants in your Outdoor Living Spaces should be to promote deep root growth.  As the roots grow deeper, you can water less frequently and therefore, conserve water.

I have three post on water scheduling that address the different mistakes made by people when watering the lawn.  I recommend starting by reading these three posts and implementing the strategies mentioned in those articles.

After implementing these strategies for one growing season, start next year again by eliminating the syringing, but by reevaluating how often you need to water. 

You may even get to the point where you only have to water your lawn once every ten days in the hottest months of the summer depending on your soil type and the microclimate of your lawn areas.

Good luck and save money and water!
