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.
The ideal time to water, therefore, is early in the morning between 4 am and 8 am. Your lawn will have time to absorb the moisture deep down to promote root growth, but will not be too damp by dark that it encourages fungus and other problems. The number of hours of continuous wetness should be kept to a minimum.
Aerate to increase infiltration. 6. Water in the early morning (4am to 10am). This allows the grass blades to dry, making them less susceptible to foliar diseases.
If your lawn is sandy, you'll probably need more water to keep it going. Test your soil to know for sure what you're working with! In general during hot summer months, you should be watering your lawn up to three times per week if there wasn't any recent rainfall.
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.
During extremely hot weather (daytime temperatures above 90F and nighttime temperatures above 70F), try to water daily or every other day. In a 10x10-foot garden, this would mean giving your plants 8 to 9 gallons of water each day.
It is ideal for watering your lawn about 1 inch of water for every single application per week. On average, it takes 30 minutes to disperse 0.5 inches of water. Therefore, you must water your lawn in hot weather three times per week, for about 30 minutes each, to get an inch of water on your lawn.
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.
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.
Watering on a hot summer afternoon is a horrible idea. The liquid will evaporate too quickly and may not reach your grass's roots, so heat and irrigation shouldn't go together. Instead, the best time to water grass during summer is in the morning. The ideal time for morning watering is before 9 AM.
A common rule that is followed for obstructions within 18 inches of the sprinkler deflector is the “three times rule”. This requires sprinklers to be positioned away from obstructions a minimum or three times the maximum dimension of the obstruction.
The “Four Times Rule” is really just an extension of the “three times rule” however it covers extended coverage sprinklers and the maximum clearance is 36 inches (0.9144 m).
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.
Nothing should be in that area between the bottom of the sprinkler heads and the imaginary horizontal plane parallel to the ceiling that is 18 inches below. This is done to allow an even and unobstructed spray pattern from the sprinklers when triggered to extinguish the fire.
1. Water Thoroughly: Rotor zones should run for about 30-40 minutes per zone and spray zones 10-15 minutes per zone. 2.
You should run your sprinkler system for as long as it takes to apply a half inch of water to your lawn. You will need to water for at least 10 minutes per week for most systems. Measure your sprinkler system's output to ensure you're not using too much water or underwatering.
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.
During extreme heat or drought conditions, the requirements rise to 2 to 3 inches of water. 2. WATER EARLY IN THE DAY You want to water when there is the smallest opportunity for evaporation and waste.
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.
While seasonal heat is cyclical, an unexpected heat wave poses a different threat, and you'll need to take more action than normal. Your lawn will likely require additional watering during a heat wave, but always water strategically.
Most lawn experts recommend watering your grass until the soil or ground temperature reaches the 40-degree Fahrenheit mark.
It is best to turn on your system during the warmest time of the day when anticipating freezing conditions. Be sure the outside temperature is 40 degrees fahrenheit or above when you run your system. You ABSOLUTELY do not want to run your sprinkler system during a hard freeze as this will cause damage to your system.
An automatic sprinkler is typically activated when the temperature reaches within the range of 135-165 degrees Fahrenheit, saturating the fire below it. Sprinkler heads have a small glass plug containing a glycerin-based, colored liquid that expands with temperature.
