Lawn Watering Tips
If you want your lawn look naturally and well-groomed, you should know when it needs water and how much water it needs. Proper lawn care, including techniques such as dethatching – the process of taking up dead grass and plant material that builds up under the grass making the soil easier to absorb nutrients – and aerating, helps your lawn grass absorb the most of the water it receives without waste.
Helpful tips on watering your lawn.
The very first sign of that you should begin a well-planned watering is a bluish-gray grass. Moreover, the individual blades of grass wilt, roll or fold in response to low water stress. Also, when you walk across a lawn, there will be footprints where the grass blades compact and low water levels prevent it from springing back up. Next, you can use a screwdriver – dig a hole 3 inches deep. If the soil is moist at that depth, there is no need to water.
Usually, the lawn needs about 1 inch of water per week, and bluegrass lawns make do with 1/2 inch. Use this simple method to determine how much water your sprinkler system delivers: place 5 to 10 straight-sided cans, such as coffee or tuna cans, in the path of the sprinkler. Let the water run for 15 minutes, and then dump all the water into one container. Measure the depth of the water in inches and divide it by the number of containers. The result tells you how much water your sprinkler delivers in 15 minutes. Multiply by 4 to get the rate per hour.
Don’t go too far with thatching – too active one can cause the water to run off instead of sinking into the soil. Dethatch the lawn when it is more than 1/2 inch thick. Dethatch cool-season lawns such as bluegrass or fescue in early spring or late summer, Bermuda grass lawns in late spring. Proper watering, mowing and fertilizing reduce thatch buildup.
The most appropraite time to water is morning when the lawn is covered with dew. If you water the lawn in the middle of the day, some of the water will simply evaporate. Also, watering in the evening doesn’t allow the grass to dry before nightfall, and that will lead to diseases.
If you live in area with clay soils, loosen the soil with a spading fork. If you lawn is large, use a power tool to create small holes in the lawn. The holes allow water to sink into the soil and serve as water reservoirs that help reduce runoff. Aerate cool-season lawns in fall and warm-season lawns in summer.
