Yard care and water savings tips
• Cover pools and spas to avoid evaporation when not in use.
• Check the level in your pool using a grease pencil. Your pool shouldn’t lose more than one-quarter inch each day. If it is losing more, check elsewhere for leaks.
• Change your lawn mower to a 3-inch clipping height and try not to cut off more than one-third of the grass height when you mow.
• Apply as little fertilizer to your lawn as possible. Applying excess fertilizer increases water consumption and actually creates more mowing for you. Use iron-based fertilizers to simply “green-up” your lawn instead.
