The issue that I am dealing with is basically one plant on the very corner of the property is not getting much water. It is on the lowest terrace of a stepped retaining wall while the sprinkler that waters that area is at the top of the retaining wall. Everything around this plant gets plenty of water, but some of them block the water from falling far enough. The home owner would like me to install another sprinkler off the end of the existing line. The problem is that unless I put it all the way down to and on top of that plant, we're going to end up with the same problem. I am wondering if it would be feasible to come off the end of the existing line with a drip line that I can run down to that one plant.
