beasts and plants require much water during the Dog Days of summer.
Irrigate lawns only when
grass blades first show signs of wilting in the morning. Apply 1/2 to 5/8
inch of water on each of two consecutive mornings to encourage deeper roots.
If you water once a week (as the municipal water monopolies recommend)
you'll promote shallow roots. During a long dry spell, as soil and subsoil
moisture levels drop, the only water available at the root zone will be
what you apply. Since typical irrigation only penetrates about 2" to 3"
into our heavy clay soils, that places a limit on the depth of live roots.
