    How much water should a lawn receive ideally...i have some people watering twice a day who have wells....seems too much. The guy at lesco said every other day for 45 minutes....when it gets real hot water daily....any thoughts?

    well with a droughtin some areas its different. best is to water a new lawn daily, established lawn every other day if dry or really warm, id say daily if its really hot.

    1" a week, preferrably in the morning to reduce evaporation is all it needs. Unless you're talking about newly seeded or sodded. If it it soo hot, the northern grasses will go dormant anyways. Every other day is excessive and wasteful.

    The 1" per week is the general rule of thumb. If it is a new lawn the 1" would preferably be light, frequent waterings to keep the seed bed wet until germination. Then less frequent, but heavier waterings would be preferred until established. Once established, the 1" would be best in 1 or 2 heavy waterings. This encourages the turf's root system to grow deeper to follow the moisture as it naturally drains deeper into the soil. The people who are watering their established lawns daily or twice a day are creating a weak, shallow root system because the roots have no reason to go deeper into the soil. When we had a drought emergency declared a couple of years ago and watering of lawns was banned it was very obvious which lawns had owners that had their sprinklers running every day. These were the first lawns to go dormant and then die off, while the lawns that had been watered correctly until then stayed green for a good while before going dormant. When the rains did come back, the correctly watered lawns before the drought were the first to spring back to green & lush, while many of the daily waterers had to replace their lawns because they were dead, not dormant.

    What about sod planted last fall? Should this take a regular watering routine - 1" a week etc? It got a good start last fall because of the mild weather.
