To have a beautiful and fresh lawn requires constant care, and watering it properly makes a huge difference. Irrigation depends on many factors, like grass variety, soil, climate and your lifestyle. Establish all these and you can determine the five fundamentals of your lawn watering: time, quantity, frequency, method and place.
You can start watering your lawn during spring, but don’t rush. Let the lawn find its balance with the soil in the beginning of this season to become more resistant once the hot summer comes. Depending on the type of grass, you can decide when is the perfect moment to start watering.
The ideal time to water the grass is in the early hours, between 3 am and 6 am. If this is too early for you, water as early as possible, before it gets warm. Watering on a different schedule leads to evaporation and loss of water, and it can also promote disease.
Turf generally needs about one inch of water a week during the growing season to stay green and grow, but there are grass varieties resistant to drought and warm season grasses that can survive with much less water. To establish the correct amount of water the soil should be soak just below the root bed. You can determine the depth with a kitchen knife for example and calculate the amount of time your system should operate to achieve it.
As a rule, you should try to water your lawn less frequently and deeply for the grass to develop strong and deep roots resistant to drought. A shallow and frequent watering schedule will not lead to good roots, as they won’t be forced to grow and burrow deep into the soil through seeking out water. Depending on the climate and season, you can water your lawn between once-twice a week and once each two or three weeks.
As your lawn might require more water than the amount provided by the rainfall, you must compensate the lack of water by using an irrigation system. This can be a sprinkler system or an underground one. Try to use a sprinkler system that applies water on concentrated patterns than the ones that cast water over long distances, to avoid evaporation.
Also, some parts of the yard may retain moisture longer than others in the case your yard contains different soil types. Also, take into consideration that some parts are under shade so they require less watering.
