Yard care and

water savings tips

Everyone likes green grass but maintaining a lawn can be expensive and time consuming.  Irrigating efficiently can produce quality grass, conserve water, and reduce your utility bill, while freeing up time for the things you really want to do. Some watering tips:

Lawns need about 1 inch of water each week.  If the weather is very hot, apply an inch of water about every 3 days.

Watering to a depth of 6 inches encourages deeper, healthier root development.  It allows longer periods between watering.

To measure the water your lawn receives, put an empty tuna can on the lawn while watering.  Stop watering when the can is full or if your notice water running off the lawn.
