You asked: What is the best time of day to water my lawn?

We Answered:

I don't about where you live, but here in the Midwest, it's a scorcher this year! And there's also a shortage on water. Even with our areas restriction on water, many people are wondering about the right time of day to water their lawns. And even though it's dry and hot out, we see nice (fairly plush) lawns still with this drought and heat. So when someone asked me when is the best time's of the day to water their lawn, I did some research and came up with some good info.

In the heat of summer, your lawn gets thirsty and can quickly dry out and scorch in the hot summer sun. To keep it healthy, green, and lush, it is important to water it regularly. This knowledge can lead you to wonder, "What is the best time of day to water my lawn?"

Without a doubt, the best time to water your lawn is in the early morning. It is even better if you can water just before the sun comes up. If you water your lawn before the sun reaches its peak and the day reaches its top temperatures, you give the water time to soak into the soil and reach your lawn's root system before the sun evaporates it. If you don't want to set your alarm clock and lug your hose and sprinkler out of the garage at 4 a.m., set your automatic sprinkler system to water your lawn early in the morning. If you don't have an automatic sprinkler system, consider investing in one. It will make early morning waterings much more convenient.

The worst time of the day to water your lawn is in the evening. While the day's sun allows water to dissipate slowly after your lawn has drunk its fill, nighttime moonlight lets water stay in the root system even after you lawn doesn't need any more. This can lead to root diseases that can quickly destroy your lawn.

There is an exception to the early morning watering rule, however. If your lawn is newly seeded or if you have a newly seeded patch, consistent moisture is best. Just be sure not to overwater or your new seeds could wash away.
