FINALLY! After a record-setting July, temps are cooling down. The transition from summer to fall can be tricky for sprinkler programming. This week (as of 8/17), we’ve begun reducing sprinkler programs by 35%-50%.
- Watering up to 4 days/week: 2 on, 1 off, 2 on, 2 off (day before & day of mowing)
- Rotors on split cycles of 13-20 min (26-40 min/night)
- Pop-up sprays on split cycles of 6-10 min (12-20 min/night)
- Drip on split cycles 15-22 min (30-44 min/night)
These guidelines apply to many landscapes but not all. It may be necessary to program for more or less water based on your site’s unique conditions.
Why are some of these times on the high side? Parts of the Treasure Valley will lose pressurized irrigation water by early September & we have no idea what the weather will be after that. We want to keep the ground well-hydrated until then.
When will our Sprinkler Techs make programming changes for full-service commercial clients? We started on Tue, Aug 17th. Most clients have biweekly sprinkler maintenance so we expect to be through all controllers by 8/31.
What happens if it gets hot again? While it’s possible to see minor dry spots where coverage is lacking, the longer, cooler nights will offset warm days. We think this programming will be fine.
What happens if it gets cold & rainy? As with all programming, we do our best to anticipate what the weather will do in the weeks ahead. It’s possible we’ll cut programming even more if conditions require it.
