When is the best time to water lawns
Correct Lawn Watering Times
Watering of lawns needs to be undertaken at a time of day when it is least wasteful, least able to cause damage, and in turn is most useful and beneficial to the lawn.
Watering should ideally be undertaken in The Morning.
Optimum Uptake Of Water For Lawns
With so much emphasis now being placed onto our use of water in our gardens, and with water restrictions now affecting the majority of Australian cities, we really do want to water our lawns at a time of day when it is most beneficial, least wasteful, and while reducing any type of possible damage to lawns from incorrect watering practices.
And the best time of day to achieve all these goals, is to water lawns in the morning.
Lawns, like all other plants, can still take up water overnight, though at a greatly reduced rate when compared to the daytime. So watering first thing in the morning will ensure the greatest take up of the water we're applying by the lawn. Watering in the middle of the day, can lead to a great deal of loss due to evaporation, which is more so in the heat of the summer months.
Watering lawns at night can also create another problem, in the form of the encouragement of lawn disease. Which is especially true over the warmer summer months when a lot of water can become trapped in the thatch layer of turf, which in turn creates a humid environment which is then a perfect breeding ground for disease.
Active Vascular System Of Lawns
The vascular system of lawns works like a blood stream, pumping nutrients and water from the ground, and distributing them around the plant. The vascular system of lawns is powered by the sun, and as such is most active during the day and slows greatly at night.
Wasting Water At Night
When lawn watering at night, the lawn can make far less immediate use of the water it is receiving, so the lawn does not absorb everything that we are applying, and the water then stays in the ground being pulled down towards the water table and away from the root zone of the lawn. So we can see how easily we can lose a percentage of our water due to waste every time we water throughout the year.
By morning when the lawn is fully active and requires most of its water, a percentage of this water has already disappeared, and cannot be used by the lawn at all. This results in an unnecessary waste of water which was never used. Leading to unhealthy lawns lacking adequate water, or too much water having to be applied in order that enough is left over in the morning for the lawn to use at its optimum time when it can be uptaken, and to show adequate health and growth for the water applied.
