Watering is critical for the health of your lawn, but it’s essential to do it wisely. Early morning is the best time to water, allowing the grass to dry out during the day and preventing diseases. Aim for deep, infrequent watering sessions to encourage deep root growth. As a rule of thumb, your lawn needs about 1 to 1.5 inches of water per week, including rainfall. Using a rain gauge can help you track how much water your lawn receives.
