When’s the Best Time to Water the Lawn? Let’s Settle the Debate Once and For All

Lawn Sprinkler Spraying Water on Grass

Early morning? Afternoon? Evening? Overnight? Just when is the best time to water your lawn?

There really should be no debating the answer to this question whatsoever.

Hands-down, the best time of the day to water the lawn is in the early morning hours, like just before or right at sunrise. The reasons for this are plentiful, and include:

  • Low wind: During late morning, afternoon and evening hours, wind can blow water from sprinkler heads away from the lawn, so the grass may actually be getting less water compared to low-wind times of the day, like early morning.

  • Maximum absorption: Everything is cooler before the sun comes up and there’s less of a chance for evaporation, so the water will do a better job of soaking into your lawn. This enables the water to better reach the grass roots to really deliver those nutrients that your lawn needs to thrive.

  • Minimal risk of disease: Another nice thing about watering right around sunrise is that it won’t be long before heat from the sun dries the lawn of its dampness. This is a good thing because if water is left to dampen the lawn for extended periods of time, as would be the case if you watered in the evening or overnight, then it could lead to fungal growth or lawn diseases.

Additional Lawn Care Tips

OK, now that we’ve settled the debate once and for all on when it’s best to water your lawn, it’s also important to share some tips  on how to ensure that your lawn is being fed what it needs:

  • Set sprinkler heads so that they’re only spraying onto the lawn itself and not onto driveways, sidewalks, patios or landscaping beds. Water that is sprayed onto non-lawn areas of the yard is basically wasted water, so be sure to adjust the sprinkler heads accordingly.

  • Get a rain gauge: If you have a sprinkler system, make sure a rain gauge is integrated with it. That’s because while all lawns need water, too much water isn’t a great thing. Rain gauges will help determine whether or not rainfall has provided an adequate amount of water and, if it has, prevents sprinklers from turning on. Water is the key cog that drives a lawn’s health, but it’s true that there can be too much of a good thing.

  • Have your sprinklers annually inspected: In addition to having sprinkler systems properly winterized before cold weather sets in, an inspection is a worthwhile investment to ensure that they’re running up to par, that all the heads are working properly, and that there are no hidden leaks in any of the underground tubing. Leaks can waste water, which means your lawn isn’t getting it.

Bottom line – water in the morning and water smart. For more information on why you should be setting those sprinkler timers for the morning hours and for some key watering tips, contact A.I. Sprinklers today.
