Yard care and water savings Tips

Practice Smart Watering for Healthier Plants

Did you know that watering too much or too little is the cause of many common plant problems?

  • Water deeply, but infrequently.  Most plants do best if the soil is allowed to partially dry out between watering.  For lawns, a loss of shine or footprints showing indicates that it’s time to water.  Vegetables and other annuals should be watered at the first sign of wilting.  Trees and shrubs usually need little watering once their roots are fully established (2 to 5 years), except in very dry years.

  • Moisten the whole root zone.  Watering deeply builds deeper, healthier root systems.  To see if you are watering deep enough to moisten the whole root zone, dig in with a trowel an hour after watering to check the depth.
