Highlights. 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.
It is often recommended that you water your lawn early in the morning, as early as 4 am and no later than 10 am. During extreme heat, watering should be done no later than 7 am.
The colder weather does not evaporate moisture from the lawn as quickly as it does in the warmer weather. Most lawn experts recommend watering your grass until the soil or ground temperature reaches the 40-degree Fahrenheit mark.
Don't water everyday.
The more shallow your grass roots are, the less hearty it will be in hot weather. Instead water about two times per week for longer periods of time. The local lawn companies I have spoke with around my area (North Central Texas) recommend about 20-30 minutes per watering cycle twice a week.
You must water your lawn in hot weather at least three times per week, as long as you soak the soil to a depth of at least 6 to 8 inches. Akin to normal conditions, watering your lawn daily will create a shallow root system, which dries out fast and weakens your lawn.
Typically, most lawn irrigation periods during the summer should last between 25–30 minutes each. This amount of time depends on a lot of different factors though. As previously stated, each irrigation system or sprinkler can deliver different amounts of water and it's important to hit that 1 inch per week requirement.
Watering early in the morning is important when it comes to keeping your lawn hydrated. The best time to water is 6:00 AM to 10:00 AM which allows the grass and soil to properly soak in the water. On the hottest days, try to mow even earlier—before the dew dries.
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.
Once temperatures reach 77 degrees, it becomes too hot for root growth, and root growth ceases. When temperatures reach 90 degrees, it becomes too hot for shoot growth and the grasses stop growing and begin to fall dormant, with the surface grass turning a brown hue.
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.
During really hot weather, water your vegetables at least two to three times a week. Watering the garden deeply is critical. The water must go down, down, down to encourage deep roots and get away from the hot soil surface.
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.
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!
Water deeply and infrequently (2-3 times per week). Morning watering is highly recommended, as afternoon watering can lead to early evaporation, while night watering can cause various forms of turf disease. Refrain from mowing too low.
Mower Height
A mowing height between 2.5 to 3 inches is best for most of the season, except during summer stresses when the lawn mowing height should be raised one-half inch to mow at 3 to 3.5 inches. Raising the mowing height provides more insulation from summer heat and reduces water loss from your soil.
Highlights. 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.
Most plants shut down during extreme heat, so if it is over 100 degrees, it may be best to wait to water even if your plant is stressed. Throw a damp sheet over it, or mist it lightly to bring the temperature down.
The best time to plant warm-season grass seed is late spring or early summer, or when temperatures hover near 80 degrees or higher in your area.
Vegetables and fruits that are developing fruit during a heat spell need regular watering to ensure good production. Vegetables typically require daily watering during summer weather, but may need a second watering when temperatures are extremely high.
If you forget or are too busy to water your plants on some summer mornings, you can water them at night. However, this should not be your ordinary watering time. Morning is the proper time for watering plants, though you should keep in mind that not all plants need daily watering.
Even in the warmest days of summer, a good soak every three or four days is best for plants because it forces their roots deeper into the soil where they are healthier and cooler.
As seasons change, resources such as sunlight and ideal temperatures cause growth patterns in the grass to change, too. Grass grows particularly fast during late spring and early summer in response to adequate amounts of water and sunlight and warmer temperatures.
Water grass between 6 am to 10 am early in the morning which is the coldest part of the day to reduce the chances of fungal problems and allow the water to soak within the day. On the contrary, watering when the sun is at its peak and temperatures are high means that water evaporates quickly rather than being absorbed.
Can You Water Grass After Mowing? Yes, you can water grass after mowing, however it is healthy to water it but only if it requires it. Watering will help the mowed blades perk up and survive being cut better. Take care not to water a lawn overwatered or from noon till late into the night.
