Mow
Kentucky bluegrass, fescues and ryegrass to no less than 3 inches. Longer
grass has more leaf surface to absorb sunglight - this helps it grow thicker
and develop a deeper root system. Longer grass also shades the soil surface,
helping to retain moisture. |

If
you haven't already done it, sharpen your mower blades. Dull blades tear
the grass, browning the edges. Sharp blades make a clean cut. |

Try
to water your lawn to encourage deep, drought-resistant roots. Choose the
best time of day to reduce loss due to evaportation. Most lawns are watered
too often, with too little water. Frequent shallow watering trains roots
to stay near the surface. Try instead to water your lawn in a way that imitates
a slow, soaking rain. Apply about an inch of water and then let your grass
dry down before watering it again. |

Use empty
tuna cans or shallow pans to figure out how much water your irrigation
system puts out in each zone in 20". Measure on a calm day so that
you can adjust your zones to what is really happening with your irrigation
system.
If you like
online tools, here is one for figuring
out irrigation times from the Denver Water Board.

Signs
of drought stress and signs of overwatering can
look the same - drooping, wilted foliage.
Check
the soil an inch or two down, if it is moist,
do not apply water.
More plants
are lost in our region due to overwatering than underwatering.
