Zones should be separated by irrigation types.
- Pop-up spray zones can be 15 to 25 minutes.
- Rotor Zones can be 40 to 50 minutes.
- Rotary Zones 40 to 50 minutes.
- Drip and/or Bubbler Zones can be 15 to 25 minutes.
Depending on the coverage the irrigation system provides for the landscaping, coverage can dictate how long to irrigate each zone. If the zone(s) provide full coverage on the landscaping, then lower irrigation times will work just as well.
The type of landscaping dictates the amount of irrigation needed as well. High drought tolerant sod like Bahia, requires less amounts of water. Sods like St. Augustine or Zosia are low drought tolerant turfs which will require the higher of the suggested times.
