In general, it's best to water your grass deeply and infrequently rather than a little bit at a time. If you water too frequently, the grass won't develop a deep root system and will die out if there is an extended drought or watering restriction imposed. By watering once a week or less, you are training your grass to develop much deeper roots that allow it to do better in periods without water. Do not water in the heat of the day, because a large part of the water just evaporates without helping your grass at all. It is a big waste of water. Many areas of the country even ban watering in the afternoon hours for this very reason. Water in the early morning, or in the evening, when it is cooler and there is less direct sun. The Better Lawn and Turf Institute also offers good information on lawn watering. Bob Vila offers this advice on lawn watering. The Turfgrass Resource Center has this guide to watering new turfgrass sod. All types of grasses benefit from high quality soil. Use an organic lawn fertilizer to improve the quality of your soil long term. Need a mower or other lawn and garden supplies? Visit Clean Air Gardening.
It depends on how much sunlight and how much rain there is. If there is alot of rain and little sunlight I would say that you don't need to water at all if there is alot of both then water maybe once a week to help it out. if the is alot of sunlight and little rain then water it almost everyday or every other day.
Watering once or twice a week should be enough. Soak the soil one inch deep each time. Watering in early morning is best. Late night watering could create an environment for fungus to grow.

A cactus should be watered at least once a week. It can be watered two times a week if the soil is very dry.
Mature lawns require 1 inch of water per week. It is best to water deep and infrequently, so you will want to water twice a week, giving the lawn a half inch of water per watering.
You can water its amount normally, but if you just planted it you should water it 2 to 3 times a week.
Jamur grass does not require a lot of water to thrive. About an inch of water a week is enough of water for the grass to grow healthy. If the grass is new or sod, the care for the grass the first two weeks requires the soil to stay moist to enable the roots to grow deep.
once or twice a week
During the summer in Houston Texas, my St. Augustine grass grows about 2 inches a week.
10 times a week
at least twice, every 2 days or so.
we blink about 5000'000 times a week
Depending upon the type of grass, and the weather in your area. For example in hot Central Texas, for St. Augustine we water our grass twice a week. We try to make sure that it gets at least 1.5" a week. Also, it is important to watch the leaves of your grass. If they are folding or curling up, they are short of water. Water them the next morning. You can place used soup cans in various places on your grass to measure how many inches of water is your grass getting. Please also be mindful of the compaction and slope of your soil. If it is compacted and slopy, then water is very gradually so the water can seep down deep, in order to get deep root growth.
