It is best to wait at least 24 hours after watering before mowing your lawn. This will give the soil time to absorb the water, making the ground firmer and easier to mow without damaging the turf.
If your lawn does need to be mowed and watered, make sure you schedule it for early in the day to avoid moisture evaporation and problems with disease. Don't water your grass before mowing. Wet grass tends to clump together on the lawn which could suffocate the grass underneath or promote fungal growth.
When dealing with mild morning dew or after light rain showers, you may only need to wait between 2 and 5 hours for the lawn to dry before mowing. With a heavier rainstorm, you should wait at least one day to mow safely. Shady areas of the lawn will take longer to dry than those in the sun.
You should water it after mowing when the soil feels dry and the grass needs hydration, as soon as possible after mowing. As your grass is freshly mowed, it needs to be watered to gain strength again and grow in a healthy way.
'As long as your blades are sharpened, and the grass isn't not soaking wet, mowing in the early morning dew is totally fine,' says Douglas Dedrick.
When the sky is clear or mostly clear overnight, the ground cools, and the warm air radiates away from the ground, up toward the sky. If the ground cools enough, dew then forms on the grass. When it's cloudy overnight, the ground retains more of its heat, and not as much heat is radiated up to the sky.
Wet grass clippings can clog your mower, causing it to choke and spit out clumps of wet grass that could smother and kill your lawn if left unraked. It's best to wait for wet grass to dry before mowing.
Avoid watering grass on a hot afternoon when it's 95 degrees or higher. The best time to water grass is at dawn or in the early evening. Water deeply three times a week instead of a little water daily. Test whether your sprinkler system is watering your lawn evenly.
Water Wisely
Most lawns need to be watered no more than three days a week in the spring as well as in the summer and two days a week in the fall. This watering schedule is recommended under normal water supply conditions.
It is ideal to water lawns about one inch of water per week. To determine how long you need to water to get one inch, place a plastic container in your yard and set a timer. On average, it will take 30 minutes to get a half inch of water. So, 20 minutes, three times per week will give a lawn about an inch of water.
The short answer: No. Mowing wet grass can be problematic for your lawn, your lawn mower and you. If you do mow wet grass, you risk leaving clumps of clippings that could smother the grass beneath. Wet grass can clog the mower, causing it to overheat, and stick to the mower's underside, which is difficult to clean.
Grass needs the benefit of the day to dry and heal before dusk settles. Since mowing your grass in the early morning can damage it and mowing it during the early afternoon can burn it because of all the high temperatures, the ideal time is mid-morning. That is of course if you're free during that time of day.
Mowing too soon, before the turf grass has begun to grow and thicken up, exposes the soil and over-wintering weed seeds to sunlight.
It's important to water deeply and infrequently to encourage deep root growth and drought tolerance. Most grasses require about 1-2 inches of water per week, which can be achieved through one or two deep watering sessions. Overwatering can lead to shallow root growth, disease, and pest problems.
Most lawns need 1 to 1.5 inches of water per week—either from rain or watering—to soak the soil that deeply. That amount of water can either be applied during a single watering or divided into two waterings during the week. Just be sure not to overwater your lawn.
Between irrigation and natural rainfall, your grass should receive between 1 and 1.5 inches of water each week during the summer. Water deeply every other day for the best results.
To correctly water your lawn look at a thermometer outside. If it's 70-80 degrees outside try watering 2-3 times a week. During the spring your lawn will be fairly easy to manage so you don't have to water all the time. In the blazing summer, when temperatures are between 90-100+, try watering 3-4 times a week.
In times of extreme heat, it is vital to water your lawn for about 30 to 45 minutes daily. Once the temperatures drop below ninety, you can cut back to watering three to four times a week, until that blissful thunderstorm comes and quenches your lawn's thirst!
It's tempting to water your lawn in hot weather, especially if your grass is already looking a bit thirsty. But in most cases, you shouldn't water your grass when it's 95°F or hotter because the water will likely evaporate before it reaches the roots.
Timing is based primarily on the growth stage of the plants to be mowed and secondarily on the growth stage of the desired plants. The most effective time to mow noxious weeds is when the desired plants are dormant and weeds have reached the flowering stage.
If your lawn seems to always hold water, then there's a yard drainage issue at play. This can be related to the way your property is graded and how water flows, where your gutters are directing water, or even what's going on at a neighbor's property (potentially sending excess water into your yard).
The dew we see and feel on the grass in the morning is linked to how cloudy the sky was the night before. When the sky is clear or mostly clear overnight, the ground cools, and warm air radiates up toward the sky. If the ground cools enough, dew forms on the grass.
Those tiny droplets you see clinging to the blades of grass are called "dew." Dew is liquid water droplets that form on grass, spider webs, and other things in the early morning or late evening. Dew only forms under certain conditions. If a warm, clear day is followed by a cool, clear evening, dew will likely form.
