When Should I Water My Grass?

Summer Watering (small)Especially in warm climates like Georgia, watering is vital for keeping your grass in tip-top shape, but it’s not as simple as buying a sprinkler system with a daily timer. There are many factors which go into providing your lawn with the right amount of water at the right time—it even varies among people who live in the same geographic area. For homeowners in the Atlanta area, our lawn care professionals have offered some general guidelines for getting a handle on when it’s time to irrigate your lawn.

Time of Day

In general, the ideal time to water your lawn is in the very early morning. If you water during the day, the sun will evaporate the water before it’s able to reach the roots, but if you water during the night, the moisture sits on the grass and makes the lawn more susceptible to diseases and fungi, so early morning is the perfect balance between these two issues.

Type of Grass and Soil

Various types of grass have very different characteristics. For instance, warm season grasses like Zoysia and Bermuda need less water than cool season grasses like Tall Fescue. As far as your soil type goes, sandier soil will absorb water quickly, so it needs frequent applications of small amounts of water. Clay, on the other hand, absorbs water slowly but holds the water for longer, so it typically doesn’t need to be watered as frequently. Keep in mind, however, that grass typically needs more water during the first year after it’s been planted or sodded in order to allow the roots to establish themselves.


Evaluating your grass and soil can give you a better idea of how much water your lawn needs, but that doesn’t necessarily mean you should simply set up a sprinkler system for 5am once a week and be done with it. If you water your grass during or shortly after rainfall, you could be doing more harm than good. Try keeping a rain gauge so you can see exactly how much water your lawn has received in the past few days, and also be sure to check the weather forecast before you water to see when the next rain is predicted.

Around your Mowing Schedule

Grass can lose a significant amount of moisture when it’s cut, so if your grass is already a bit on the thirsty side when you cut it, you may find yourself with not just a perfectly cut lawn, but a brown one. Make sure your grass is thoroughly hydrated before you bring out the mower.

Lawn care is a task many homeowners underestimate. They expect to simply mow every week or two and perhaps add some landscaping. But for those who want to enjoy both the appearance and the feel of a lush lawn, doing your research and working with an experienced professional can mean the difference between a lawn that’s simply grass and one that’s truly an extension of your home.
