How to Stop Overwatering a Lawn

In times of drought and little rain, it is tempting to water the lawn too much, trying to make up for the lack of rainwater. However, the irrigation that happens from a good rain is not the same as the forced deliberate water that comes from a sprinkler or hose. Use some of these tips to grow lush green grass and stop overwatering your lawn.

Difficulty: Moderately Easy

Instructions

1. Use a small can such as a tuna fish can to measure the amount of water your lawn is getting. Put the can under the sprinkler and when it is full, turn off the water.

2. Watch for runoff. When you see water start to run into the street, it's time to turn off the sprinklers. The grass will only keep as much as it needs and the rest is wasted. Areas that cannot drain will collect the water and turn to mold.

3. Turn on the sprinklers only one day a week for a good, deep watering instead of light watering more often. Deep watering about four to six inches is better for the roots and the lawn can drink for days as the water rises to the top.

4. Water your lawn early in the morning or in the early evening. Too much water evaporates during the strong heat of the day. The water will be wasted and areas that may be in shade will get too much water. Keep it as even as possible to avoid overwatering some spots while others go dry.

5. Seed the lawn in late summer with a drought resistant lawn seed such as fescue so that your lawn won't need as much water the following summer.
