What Does Watering Deeply Mean? There is no hard-and-fast definition for watering deeply, but it generally means that the water can soak at least eight inches below the soil surface. The reason behind watering deeply is that most plant roots are not sitting close to the soil surface.
A related question is how often to water your lawn. You do not have to provide the required 1 inch per week all at once. Instead, you can water for 30 minutes twice a week. But some experts advise against extending irrigation sessions beyond that (for example, watering for 20 minutes three different times a week).
To see how deeply you're watering your plants, a soil probe will give you the most accurate reading. Soil probes are specialized tools created just for the purpose of measuring your soil's moisture, but a long screwdriver can also do the trick.
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. This formula works best with healthy, well-cultivated soil.

1) Watering for Too Long
This should be no more than three times per week. Set a timer for 20 minutes and stick to your schedule, even if you think the lawn needs more water. You don't want to oversoak it.
Generally, deep watering means that the soil is saturated to about an 8-inch depth. Healthy plants usually grow their roots down deep.
Watering the grass every single day for 15 minutes.
Instead of watering shallowly every day for 15 minutes, water deeply once a week for an hour or so (or however long it takes to apply an inch of water).
Shallow root systems require frequent watering to keep the surface wet, creating an ideal environment for weeds and diseases. Although some grasses have less extensive root systems than others, deep, infrequent watering that allows water to penetrate the top 6 to 8 inches of soil will promote healthy root growth.
Check the leaves for wilting and test the top inch of soil with your finger to see if it's dry enough to need a drink. Test Garden Tip: You're more likely to overwater indoor plants than underwater. Too much water will drown your plants. A good rule of thumb is to let the top inch of the soil dry out between waterings.
Therefore, 1 inch of water will need to be applied to wet the soil to a depth of 6 inches giving a run time of 1 hour. If you find you're getting run-off before you saturate to 6-inches, you can split the cycle up into two sessions with a break in-between.
Let's say you want to provide 2” of water to the raised bed: First, multiply the . 62 gallons of water for every inch needed (. 62 gallons x 2 inches) = 1.24 gallons for 2” of water per square foot.
Sprinklers should be set to run for about 30 to 35 minutes at a time twice a week. Your goal is at least 1″ of water a week for your lawn. When it's hot and dry, double the water times while still trying to water just 2 or 3 days a week.
Deep and infrequent irrigation
The concept is that you apply a large amount of water (1+ inch) perhaps once a week (or when the grass starts to show drought stress) to wet the entire soil profile, and as the top dries out, the plant is forced to grow deeper roots to utilize the water further down in the profile.
Generally, light, daily or frequent irrigation keeps the top one to three inches of the soil moist, while deep, infrequent irrigation waits for signs of the grass wilting before applying enough irrigation to wet the soil to a depth of 10 inches or more.
Most grass needs watering between 20 to 40 minutes at a time. Water your grass one to three times a week in peak growing seasons. Your grass type, region, and amount of rainfall impact watering times. Watch out for signs of too much or too little watering to avoid disease or dead grass.
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.
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.
Therefore, an “inch of water” is 0.62 gallons per square foot of garden area. Unless you use a gallon jug to water a square foot garden, this number may still leave you wondering how to obtain that inch of water or 0.62 gallons per square foot.
The grass plant therefore relies mostly on its root system for moisture and not on the grass blades. Although there is some absorption of water and nutrients through the blades, they are mainly for food production through photosynthesis, and in transpiration of water up from the roots.
Not only is deep root watering trees the best way to get your trees quenched and thriving, but using the right deep root watering system is the most efficient way to do it. It's also great for the environment because you'll be using less water.
