That's right. Lawns watered more than once a week don't develop the strong, deep roots needed to thrive in Texas. An inch of water every week to 10 days is plenty to keep your lawn green, plus it encourages a sturdier root system to help your lawn through the summer. So here's a tip: place a tuna can somewhere in your yard when you're watering. Once the can is full, that equals 1 inch and your lawn's had enough. Doing this saves you water and money.

Remember the city watering guidelines:

* From June 1 to Sept. 30, water only before 10 a.m. or after 6 p.m. when using sprinklers. Watering with a hand-held hose or soaker hose is permitted at any time.

* Water just your lawn, not driveways, sidewalks or streets.

* Promptly repair broken or leaky sprinkler heads and systems.

* Turn off sprinklers when the forecast calls for rain.

In addition to these guidelines, Dallas residents are finding all kinds of ways to save water. So what are you doing?
