Watering is the single most important factor in the health of your
lawn and landscape. With proper watering, our programs will deliver
excellent results.
How Often?
Basically, you should water as often as needed to prevent wilting or
drought symptoms. This will vary with the seasons, with summer of course
being the time of year when more frequent watering is needed. As temperatures
rise, plants moisture requirements increase, and more water is lost through
evaporation.
Watering thoroughly once or twice weekly is usually sufficient during most of the growing
season. However, during extremely hot and dry conditions watering every other
day may be needed to prevent wilting. Shrubs and trees generally require less frequent
watering due to their deep, extensive root system. As with turfgrasses,
certain trees and shrubs are more drought resistant than others.
During periods of regular rainfall, less watering by you will be required.
When?
The most important concern about watering is that you water when needed!
Some times of the day are better for watering than others, but it is better to
water at any time of the day or night when you can than to not water at all!
That said, the most optimum time to water is early morning (from 3:00 AM to 8:00 AM).
There is less evaporation loss during this time. Also, avoid watering in the
early evening if possible, as this can encourage fungus to develop.
How Much?
Lawns generally require one inch of water per
week to remain green and healthy. This can come from natural rainfall,
irrigation, or a combination of both. You can measure the amount of
water your sprinklers deliver by placing a container underneath and recording
the amount of time it takes to accumulate one inch in the container. If your
sprinklers deliver one inch of water in two hours, you might want to water twice
weekly at one hour per each watering to deliver the total of one inch of water to the
lawn.
Avoid light waterings. These encourage shallow
roots. Heavier waterings that soak deeply into the soil are best because
they encourage deep root systems.
The optimum amount of water to apply to lawns in this area is one half inch per
watering twice per week.
Automatic Irrigation Systems
If you have an automatic irrigation system, we recommend the following general
settings:
Frequency: twice weekly
Start time: 3:00 to 8:00 AM
Zone run times: Rotating heads-60 minutes. Spray heads-20
minutes.
