Early Spring
Generally, we are receiving enough rain this time of the year to take care of any watering that is necessary, but if it does not rain within one week after your application is done, your lawn will need to be watered.
Spring
Should it not rain, you will need to water your lawn within one week after your application is done. Water infrequently but deeply. The water needs to soak 4-6 inches into the ground to encourage a deep root system. Too much water can cause problems, such as increasing the chance of fungus, or run off and leaching of nutrients. Morning to midday is the best time to water.
Summer
Your lawn should receive roughly 1 to 1.5 inches of water per week during the hottest, driest months. Deep watering to a soil depth of at least six inches is recommended. Light watering is of little benefit and can actually harm your lawn.
Winter
Your lawn needs water during the winter months for the roots to remain healthy. Adequate watering will protect the roots from drying out and damaging the grass during a hard freeze (which is known as “Winter Kill”). Your lawn will need water if it has not rained in two or three weeks.
