Personally I would use the lowest flow necessary—.5 gallons/hour.

Attach 1/4” tubing to the emitter thus you can move the location of the water delivery as the tree grows. I have three emitters per tree. The length of the 1/4” tubing ranges from 8” to 30”. The flag emitters can swivel around. This does not follow the instructions that come with some emitters. This is what he uses at the nursery to water potted trees but with the barrel style emitter.

Lets say I had 20 rows of trees each with 10 trees.
I would give each row their own independent line.
I would then have each of 20 lines connecting connecting to a main line on the right.
I would then have another main line on the left to equalize the pressure.
I would put a switch at each end of every row so that I can independently work on each line.

Based on your winter low, you are in Zone 8, with a climate similar to Seattle/PNW.
But it sounds like you are going to need a water heater. I like this system

This is a great device and the wonderful part is that it is low wattage only a 183KWH per month aka 250W

With such mild climate it might be that it will never freeze, esp if a bubbler is used.
