Splitting an irrigation zone
You need to run a new main line from the zone valve to the last sprinkler of the planned first half zone. This ties to the main line continuing to the new second half zone.
While this can run in the original trench, you still have to dig it up again.
YOu might look into smaller gallons per minute sprinkler heads to replace those on the planned second half zone which would save the need for digging. This method would require the same time schedule for both halves. Larger gallons per minute for the first half will probably not work because of insufficient water pressure.
The disadvantages of crab apple trees. In summer, the apples are too sour to pick and eat. In winter the birds come and leave dropping all over the place.
