Irrigation & Water Restrictions

 

Saint John's Water Management Regulations

Water two days a week: Odd number houses, (Wednesday & Saturday), even number houses (Thursday & Sunday) before 10:00am or after 4:00pm.

 

During day light savings times November-March water one time per week only.

Watering in the A.M. is preferred to prevent water evaporation and also some diseases. Water 3/4 of an inch twice a week; unless you get rainfall that equals this amount. If you have a rain sensor, set it to 1/2 an inch, so the system will shut down when you have rain accumulation. If you do not have a sensor we recommend purchasing a rain gauge. Place the gauge in an area that you frequent often, so when you receive 3/4 of an inch of rain you can manually shut down your system or skip a watering.

 

 

 

 

Estimated Run Times

Pop Up Heads (heads that do not turn, or stay in one place): Water 20-30 minutes.

Rotor Heads (heads that turn and water larger areas): Water 45-55 minutes.

 

These are standard times and offer a starting point for calibrating your system. You also need to account for seasonal rain, heat, and soil type. Areas in direct sunlight will require more water and are more likely to have what we call HOT SPOTS, or areas that just cannot retain enough moisture. Shaded and lakeside properties will retain water longer, zone run times may vary and you should adjust accordingly.

 

 

 

 

Calibration

Calibration is a critical aspect of irrigation systems. By calibrating your own irrigation system it will allow you to know exactly how long each zone needs to run to achieve you target volume. Collect some tuna or cat food cans, measure and mark 3/4 to 1 inch of water. We also offer our customers measuring cups that have a steam so they are held firmly in the ground. If you wish to use these cups just call out office (407)-737-1889 and your technician will bring you a pack that includes instructions.

 

After you calibrate your system, look for results over a period of two weeks. You might find dry spots in a zone that needs attention. Make sure you are getting good overlap water spray; all heads are turning and plants are not blocking any heads. This will take time, but the end result is well worth it!

 

 

 

 

Deep Watering Benefits

Deep watering (getting soil wet 6-8 inches deep and watering less frequently) is also preferred to shallow watering for less time, only wetting the surface soil.

  • Promotes deeper turf roots and creates a stronger healthier plant.
  • Prevents weed growth (weed roots are shallow and by watering deeper, you are not watering the weeds).
  • Prevents mold and diseases.
  • Prevents dry spots (retains moisture longer).
  • Mulching shrub beds 3-4 inches deep will also help maintain moisture and prevent weed growth.

You will find seasonal recommendations for how much and how often to water based on the water conditions at that time in each of our seasonal newsletters.
