The droplets of water that remain on the grass, plants and flowers actually wilt the plant once the hot sun warms the water. Most of the water that is being put down is also being evaporated due to the heat. It is best to water in the early morning or early evening hours, but never late in the evening. This will give the ground a chance to soak the water in and reach the root system of the plants. Watering late in the evening could possibly cause more disease and weed problems as they tend to develop more at night than during the day.
Most lawns require a minimum of one inch of water per week.
This can be accomplished by watering each section for one hour at a time. Once the can is full you have reached one inch. It is best to water in this manner 2 -3 times a week if possible. Rain is the best supplier of water due to the natural occurrence of nitrogen, which is essential to the health of your lawn. It is hard to ensure that your lawn is getting enough water in some cases.
