There are many aspects of lawn care needed for success, one step that should never be forgotten is watering, you should always do this in the morning. The reasoning behind early in the morning revolves around sun damage. The water’s reflection has the power to reflect off the sun and heat up the grass. By watering in the morning, the sun is not as high in the sky and it is not as powerful. If you were to do this later in the day, say around lunchtime, you put your lawn at risk for sun damage—which can causes discoloration along with other negative effects.
