H2o My Lawn Or Water Smarter?

GreenThumb Nurseries' newsletter suggested longer and slower watering which is initially contrary to edicts by the municipalities; but over the long term will enable you to conserve water.

"...try watering for longer periods with a sprinkler that delivers slower water..."

"...3 or 4 hours once a week essentially mimicking a slow and steady rain fall."

AND THEN SOME MOST SURPRISING PIECE OF INFORMATION:

"... over time, the roots will go deeper, and not depend on as much water"

"best to water your lawn in the early morning time because less evapotranspiration ( read on for more information) occurs during this time. 

"let your grass grow a little longer to help conserve moisture"

AND AN ALTERNATIVE:

  • Typically, older trees and shrubs need less water than shallower rooted plants and new plants
  • Instead of removing the entire landscape and installing drought tolerant plants consider removing plants that are crowded or overgrown which are competing with other plants for water and nutrients. 
  • It may sound contradictory but the more plants you have the less water you will need to apply!
    • A denser plant canopy over an area increases the humidity
    • Makes the area cooler
    • Reduces evaporation
    • Shades the soil creating a microclimate where the ground stays moist and cooler longer
