So let’s first explore the main topic: Is It Bad to Water Grass at Night?

The main issue prevents the lawn owners from day time watering is the immense evaporation. So after finding the day time extremely unfavorable their second choice would be the night time. Because they think the temperature is low, there is no sun so there is no water evaporation. But the water treatment of grasses is quite different from plants and trees. For grasses if too much evaporation is bad then no evaporation is worst.

During night time the temperature materially drops down so there is less water absorption by grass roots and soil. So the water stays stagnant for hours, provides different types of diseases especially fungal and bacterial disease a breeding space.

When you water your lawn in hot sun the water quickly absorb by soil and some evaporates so there is less chances for these diseases to develop. Moist places are favorite breeding spots for development of these fungus and bacteria. So watering your lawn during night time is the worse idea when compared to day time.

So the question is: if the night and hottest part of the day are not the options for watering your lawn then what’s the available option?

Suppose if you are living in the warm zone and the weather is now extremely hot. Then how will you find the most favorable time for watering your lawn. So the day time can be divided into the following slices based on temperature and sun intensity;

  1. Early morning
  2. Later morning
  3. Middle of the day
  4. During the afternoon
  5. And early evening before the sun sets

If you water your lawn in the above-mentioned day’s slices from 2 to 5 then you’re just allowing evaporation of a substantial amount of water. Your grass will soak a little amount of water and so the benefit of this watering exercise will be materially low. Because despite heavy watering your grassroots remain thirsty; the problem is more adverse when the temperature is very high and rainfall is very low.

So you have just one option left and that is early morning. Set your lawn sprinklers at this period of time for watering your lawn. The temperature is low at this time and also the wind is low so the droplets do not deviate from their targets. The soil and roots have a sufficient amount of time to absorb the water before the hot sun starts the evaporation.

If there is more water than the absorption capabilities of your lawn then when the sun becomes hot the extra water will vanish due to evaporation and there is no stagnant water to create an environment for the development of different types of diseases.
