During the germination stage, you must ensure that the soil not only receives enough water but the correct volume at the appropriate time.

What Would Be The Best Time Of Day To Water A Lawn To Minimize

Watering during the early morning or late evening reduces the amount of water wasted when you water your grass over a long period. Watering your lawn when the grass is still wet with morning dew reduces disease.

How long should I water my lawn every day?

Why You Cant Stop Watering Your Lawn In The Fall

Fall lawn care is more than just watering. Its also a good time to aerate, fertilize, reseed and treat for weeds and pests. Its even a great time to plant some varieties of cool-season grasses.

This window of seasonal change represents that last and best opportunity for recovery before winter, says Dr. Frank Rossi, chief science officer at Sunday. The best natural defense for spring weeds and other lawn problems is to patch and seed a healthier lawn today.

Grass seed and fertilizer need water to work. Rossi recommends the Sunday Smart Lawn Plan for getting the right fall grass nutrients.


Besides its importance in lawn care tasks like fertilizing, water helps your lawn recover from the summer. And even if your turf grass growth slows in the fall, it will grow some. It needs water to do that. Typically, the lawn requires one to 1.5 inches of water per week, says Fernandes.

Adjust your watering based on rainfall. If it tends to rain more in the fall in your area, youll likely water less. So if you get 1/2-in. of rain per week in your area, Fernandes suggests resetting your irrigation system to water only 1/2-in. to one inch.

Temperature is another consideration for fall irrigation. Grass dries out much more quickly in the summer heat. As temperatures cool during the fall, your lawn will need less and less water, Rossi says. Gradually reduce your watering as temperatures drop to match your lawns need.

It is important for the grass seeds to germinate fast for the soil to be moist so that they can easily draw water and nutrients from it. This should act as your rule of thumb in terms of your irrigation regime as both underwatering and overwatering can be detrimental to the health of your lawn.


In dry arid climates that could mean that you have to water far more regularly than in wet temperate conditions.

After the grass germinates you can start to reduce the number of times you are watering and a couple of weeks after that you should be in a position to let the grass tell you when it needs watering.

The Sprinkler System Effect

The reason why your lawn isnt receiving the correct amount of water is because of your sprinkler system. Unfortunately the hose-end sprinklers you pick up at your local hardware store rarely distribute enough water volume per square foot. Because of this, for you to reach the one-inch mark or more of water per week, you may have to leave that type of sprinkler system in one area of your lawn for hours at a time. Using the water calculation technique we described earlier will not only help you figure out how much youre dispersing and how much money you need to spend to reach that mark, but how long it takes to do so.

To make life easier, install an irrigation system if you can, and its even better if this is hooked up to a well. These systems can more evenly distribute a larger amount of water over a much greater area in less time. If you do opt to install an irrigation system, remember to have the heads adjusted properly so it releases the needed amount of water. Often irrigation companies will set the system heads to a default setting.

Figure The Water Output Of Your Sprinkler System

To calculate how much water your sprinkler system puts out per hour, place six straight-sided containers of the same size and shape in one area of the lawn where your sprinklers hit and run your sprinklers for 20 minutes. Measure the depth of water in each container with a ruler and calculate the average depth across the containers.

Multiply the depth by three to figure out how many inches of water your sprinkler system puts out per hour. For example, if the containers each had , ¼, ¼, ¼, ¼, and inches of water, the average water depth would be ¼ inches, and your sprinklers water output would be 1½ inches per hour .

Watering At The Wrong Time

To water well, timing is everything. Water in the early morning between 6 a.m. and 10 a.m. Midday watering leads to wasteful evaporation, while nighttime watering causes droplets to cling to grass overnight, increasing the chance of lawn diseases.

A Dual Outlet Electronic Water Timer will prove handy for those mornings you are away or want to sleep in. Just program the start time, frequency and duration of watering, and let the timer take care of the rest. The dual outlets make it easy to hook up two hoses at once and program separate schedules for different parts of the yard. We suggest attaching a Flexogen Super Duty Hose, as it easily curves around the yard without kinking and connects to a spigot without leaking saving water and money.

How Long Should I Water My Lawn Each Week

Since lawns need 1-1.5 inches of water per week, many factors determine the amount of water your grass requires weekly. Watering 2-3 times throughout the week instead of daily or only once per week is the best way to keep your lawn consistently hydrated. Each time you water, it is generally recommended to water your yard so that the soil is wet 6-8 inches under the surface.

The size of your lawn will be the most significant determining factor in the time it takes to water your lawn weekly. To develop a baseline of how long your lawn should be watered, calculate how much water it takes to reach the 6-8 inches of soil wetness. This baseline will tell you the right length of time to water your lawn each week.

A simple way to calculate this is to set a timer for 15 minutes and water your lawn during this time. Next, determine how far the water has seeped into the soil by placing a screwdriver into the ground, remove the screwdriver, and measure the inches down it is wet. Add or subtract time from the 15 minute interval to reach the soil wetness depth, and apply this interval to the other areas of your lawn.

Other Watering Guidelines To Consider:

  • Proper watering is critical to your lawns health and vigor. Deep and infrequent watering is the best practice. During the hotter months of the year, the lawn will require more water, so that may mean ¾ of irrigation at a time rather than the ½ of irrigation typically required in the cooler months. This means wetting the soil to a depth of 4-6 inches per irrigation.
  • Water at times of low wind.
  • Water during the very early morning rather than in the afternoon or evening to minimize the risk for disease.
  • To reduce water runoff and to help water penetrate and soak deeply into the soil, we recommend a Cycle and Soak watering schedule. Instead of watering for a long period of time and allowing the water to run off into the street, divide the total watering time per zone by 3. Water 3 shorter intervals . For example at 3am, 4am, and 5am, before winds pick up. Each cycle, water for 15 minutes for rotor heads, 8 minutes for stationary pop-ups, and 30 minutes for low volume MP Rotator heads. Water less in shaded or poorly drained areas.
  • Do not water every day or two. Frequent, short watering encourages shallow roots, unhealthy grass, plants, and leaves turf susceptible to drought, weeds, and disease.
  • Water newer trees using soaker hoses or direct hose drips once every couple of weeks.
