I water my lawn regularly and I'm mowing every other week sometimes every third week. the longer the grass the more water it will soak up and the less I will have to water.
I water 2 times a week for up to 4 hours a time. lawn is the best looking lawn in the neighborhood. my lawn looks better than some of the people who have an irrigation system because they are still insisting there lawn get cut weekly.
the drought and high temps are really taking a toll this season.
