Observations:

  1. Many plants were installed in last 12-18 months, so watering is more frequent than otherwise necessary.
  2. During winter months (November to February), reduce by 50%.
  3. During spring months (March to May), reduce by 25%.
  4. Zone 4 is not propertly hydro-zoned.  We have water needy azaleas on same drip as drought tolerant manzanitas.
  5. Long term — separate the main line that feeds the irrigation and the rest of the house.  Install meter to monitor usage.
  6. Query whether some of the main line feed to irrigation is going through the whole-house water filter. Need to figure that out.
  7. Check all zones monthly to ensure no popped or broken sprayheads, etc.
