Under our climate conditions, residential lawns need 2 to 3 cm of water per week when hot and without rain at all. This means that lawns do not need irrigation when daily temperatures are 10 degrees Celsius for a week without rain. Yet some people irrigate their lawns no matter the amount of rainfall and temperatures.

Over irrigation keeps too much water in the soil that rots the roots. In addition, the continuous wetness of lawn through irrigation favours fungus infection causing diseases.
