The trees' driplines are currently, wider than their roots. This, because they were harvested with a clamshell machine that cut off everything outside about a 16" clamshell digger bit. Those need to regrow. Watering outside the 16" root circle is needed to encourage roots to grow out TO the dripline.
But the dripline will change as the above-ground part of the tree grows. They will widen, eventually touching each other. This is why water is needed between the trees and outside the current dripline.
Right now, the roots are confined to a 16" circle. Which is, basically, the reason why I need a 30" wide wet area.
These reports of uneven water distribution from the Rain Bird 1/2" drip tube....are unsettling. Baz?
Targa, I would not expect better distribution with lower pressure. I would expect the opposite. If there were 60 psi of pressure in the hose, then that same pressure would likely be found at the end of the hose. This is a question I will be asking: Can this system have full (city water supply) pressure inside the line?
