Water Your Lawn Deeply & Infrequently!

One of the worst environmentally impacts caused by lawns comes from watering.  Most people water their lawn on a daily basis.  This daily watering is usually done  during the day or in the middle of night and lasts for sometimes 30 minutes to an hour and a half!  So what should you do?


WATER DEEPLY AND INFREQUENTLY!

Most lawns, even during the summer heat, only require one inch of water to thrive.  So where does all that water used by your neighbors go?  Most goes into the atmosphere through evaporation.  Another large amount simply becomes run-off and goes down the storm drain.  The last is collected deeply in the soil where most grass cannot reached (especially if growth is stunted with synthetic fertilizers...more on this later).  So don't waste water and your money on this ineffective technique.

The best way to water is two to three times a week for a twenty minutes.  This will easily provide the inch needed for the lawn.  You should water your lawn one to two hours before sunrise.  This is ideal for photosynthesis because you have both water at the root level and sun coming in for the maximum time period.  Let the soil dry between watering to prevent disease and conserve water. Using this simple formula you will be able to reduce your water use and have a vibrant lawn all at the same time.

Watering the lawn!

Where I live in New England, we almost never water our lawn and it remains green because of the humidity and occasional summer storm.   Sometimes I still see people with their lawn sprinklers on and I wonder why because our grass is always green in spite of rarely watering it!  Or sometimes they have it on timers and the sprinklers will go off during a thunderstorm!  Talk about a waste.

Great Point

Remember this is a general tip so it may need to be changed for your specific climate conditions.  But even in areas with high heat and low humidity, the type of grass can make a huge difference.  More on that front tomorrow!
