how long do you water your lawn for ??

You should soak your lawn well less often rather than sprinkle it lightly more often. If you are in an area where it is really dry, conserve your water and don't water the lawn at all. Dormant is better than just a little tease of water now and then. Dormant grass will come back when the rains do.

Too many variables to give you an answer: how fast does your sprinkler system apply water, what type of soil, how much do you need to apply to make up the EP (evapotranspiration loss) plus plant useage, etc.

So........you want to apply water slowly enough that it doesn't saturate the soil and begin to run off. You want to run it long enough to moisten down several inches intially. Then after about 4-6 hours the moisture should have moved down about 6-8 inches (get a long shank screw driver and push it into the soil....it will slip easily in wet soil).

If that's too hard.....take some tuna fish cans, empty, and place around the yard. Water until you get at least a half inch. Then depending on temp, wind, humidity, watch the lawn as see when it asks for more......1 day, 2, 3, 4 days???

How often you water will change with the seasons

and soil type. First determine how much water is applied

during your watering period. Set straight-sided

containers like cans around the lawn and turn on the

sprinklers for your usual watering period. At the end

of the watering period, measure the amount of water

in each of the cans. (If the depths vary widely, the

sprinkler system needs adjustment. Adjust or replace

the sprinkler heads as described below to get more

uniform application, then do the can test again). Use

the average amount of water in the cans to determine

watering frequency.

In the hottest part of the summer, bluegrass will use

1/4–1/3 in. of water per day

Til its nice and squishy. Not flooded. If you use a sprinkler maybe move it after 45 min. So it can get a good drink!
