Lawn Care Tip #3: Watering your Lawn
Most lawns require 1 1/2″-2″ of water per week. This is enough water to moisten the soil to 4-6″ below the surface for clay soils and 8-10″ for sandy soils. Don’t guess at how much water your lawn is getting. For measuring Mother Natures contribution, invest in a rain gauge. If at the end of the week she’s contributed enough, hold off adding more. If she comes up short, you’ll want to add some supplemental watering.
Again, measure how much water your sprinkler is putting down. A lawn which is under water stress, is more prone to disease, insect problems, and weeds. It is better to water early in the morning, when your lawn is normally wet from dew. Avoid watering midday due to evaporation, and at night due to potential increased chances of diseases.
