A lawn under water stress is more prone to disease, insects, and weeds. Avoid water stress on your lawn by following a few basic watering guidelines.
HOW MUCH: Most lawns need at least 1” of water per week to avoid water stress. You can measure by placing an empty food storage container under the area being watered. Once the container has 1” depth of water in it, move the sprinkler to another area. You can also test by inserting a screwdriver into the soil to see if it penetrates easily. If so, rotate the sprinkler to another section of lawn.
Saturate to a depth of 6-8” when you water. Grass suffers more from too shallow watering, water longer in each area. Also, water extra along curbs and pavements. These areas heat up quicker and dry out faster.
WHEN: Water your lawn early in the day. Early morning watering ensures that the water goes down into the roots instead of going up in vapor. You want to water when the least amount will be lost to evaporation. Also, you may think watering at night is best because it is cooler, but watering at night promotes disease and mold by allowing the ground to stay wet for too long.
