I am about get installed 3 zones of rotors on what will be bermuda sod and 6 zones of spray heads in the flower beds. What times do you guys set on rotors and spray heads for new installs? Its been hot and dry and I want to make sure that I'm putting enough water out there. Also how would you go about irrigating this the next month as far as cutting back on the times and frequency.

See if the contractor can give you accurate application rates for each zone. If you are applying water at .5"ph then you'll need different times from a zone applying water at 1.2"ph.

And take into account that red Georgia clay and how it doesn't perk very well.

You may want to "cycle and soak".

It depends on your soil.
Most just do 30 minutes a zone but they end up with a lot of run off.
It is a waste of water.
Do 2 cycles spaced apart too achieve the required amount of water.
Do not water at night.
I prefer a early morning and a mid day .


On new sod installation water as much as possible the first week.
The sod farms water 24/7 so the grass is used too it.
You can back off after that.

Good description.

I would be surprised if the contractor even considers this.
After reading how you pros do it here I have come too the realization that most people are hacks here in my area.

The soil here causes many problems that irrigation contractors just have no understanding of.
They treat a property as if it is a 2d sheet of paper.
The soils lack of perk or ability too absorb water cause immense runoff with extended watering times.
Hilly areas end up with little water and puddles down low.
Water running down the street is a norm as well.

People wonder why we are on a state wide water restriction for the last 8 months.

Not sure I agree with this.

1) Do as many starts as necessary to maximize your AE. If this means 5 start times, so be it.

2) Sometimes you have to water at night. If I start my first cycle at 3AM, is this considered night?

3) watering early morning, absolutely, mid-day, not so much unless your trying to establish new plantings. For any above ground watering, I try to make sure my last cycle finishes by 10AM if possible. This way you minimize your evaporative losses.

I agree with your assessment of irrigation scheduling as a whole. More times than not it is done improperly.

Bermuda here has a problem with Dollar spots and night time watering and low nitrogen contribute too it heavily.

I agree with trying too minimize evaporation loss.
It is a comprimise.

Thats pretty much the way we set em. 5 am for under 8 zones earlier for bigger.
No mid day .
If watering at night have cycle complete before nightfall.
Set a 7 or 8 am on program b and enter time into trouble areas only.

Hoe much bermuda grass do you have in your area?

the optimum time to water is one hr before sunrise

20x3 for rotors.
7x3 for sprays.


If in clay. Let it ride.
