Additional Watering Tips 1. Remember, less is better than more for both a healthy lawn and for water conservation. Always water until the root zone is moist. All grasses should be watered well in the fall. Even dormant grass continues to lose water and can be injured if it gets too dry.
Water soaks into different soils at different rates.
If your soil is sandy, watering for 30 minutes per week should do the trick. Loam and silt loam require about two hours to soak to acceptable depths. Clay requires about five hours of slow watering to soak in. Time how long it takes to fill the cans to a one-inch depth. If puddles form or runoff occurs on the lawn before a one-inch depth is reached in the can, adjust the watering rate.
