Lawn Watering Tips

Lawn WateringLength of grass
Keep grass at 3.5 inches in height to encourage deeper roots, shade the ground and retain more water. Aerate your lawn to help water infiltration.

How much water is needed
Established lawns in most areas require only 1/4 to 1 inch of water per week, including rainfall. Overwatering is detrimental to the lawn, as it encourages shallow, weak roots, as well as fungal diseases. Use a can or other measuring tool to determine how much water your system puts out in a typical watering cycle.

How long to water
Determine how much water your lawn receives during watering by placing a bucket or shallow pan on the lawn. Time how long it takes to fill the pan with the amount of water you have determined your lawn requires. Use this information to avoid excessive watering.

Best water cycle
Infrequent, but deep watering cycles are best. Letting the upper layer of soil dry out between watering will help prevent weeds from sprouting and lead to a healthier lawn.

Best time to water
Water in the early morning. Afternoon evaporation rates are very high, requiring more water to get the same amount of water into the soil. Early evening and night watering can be tolerated, but the lawn may remain wet longer, promoting lawn diseases and fungus.
