I have 8 zones. 1–6 are Cool Season Grass, and run every few days or so, according to the weather.
Zones 7 and 8 are drip irrigations zones supplying a variety of shrubs, flowers, and trees. Since there are many different plants in each of these zones, I set their Zone Type to Shrubs, and Spray Head to Emitter.
The area of Zone 7 is 3670 sq ft and Zone 8 is 1900 sq ft. I set both of their Nozzle Inches per Hour to 0.5.
The problem is that the two drip zones rarely run. They last run on 7/3 (I actually had to run them manually; they hadn’t run at all when we had gone for a 10-day vacation), and they are not scheduled to run again until 7/16. My feeling is that they should run for roughly and hour every day or two; it’s been very hot and dry here (Colorado).
Any suggestions as to why these two zones are not running often enough?
