I need to do this ... on a few properties .

They took away the forest behind my back fence and replaced it with large ugly two-story homes on postage stamp lots looking down into my fairly shallow back yard. Enough to make baby Jesus cry.

Emerald Green arborvitae trees are about $35 for 5' and $70 for 7'. If you will plant a lot of them (like me) in rock soil (like mine) then I strongly recommend renting a large auger. I rented one from Home Depot that is towed behind a pickup. 16" auger bit. Saved me a LOT LOT of time and frustration.

Do a loop around the base as wide as the trees current drip line.

Can be one contiguous run.

You don't need drip nozzles or anything fancy.

Any further descriptions would be helpful, as I do not fully understand. You and wdfifteen seem to be pointing to the same system. Looking at the link, the 50' roll seems to be a different animal from the 100' roll. One seems to have dribble sections and the other does not. There are connectors and plugs which are often bought at the same time, but I do not understand what they do. Perhaps start by describing the system. One long line with dribblers every 6"? Or a non-porous trunk line with separate branch lines for each tree with (maybe) dribble nozzles? Pressure regulator?

Perhaps I should just do some reading. Rain Bird probably has educational material.

Another concern I have is this: I would expect the flow rates at the end of the line to be far lower than at the start. I have basically 150' of trees here.
