Let’s have a look at how the living plant life—the target beneficiary of the Extreme Irrigation renovation—is doing two years after all the important pieces were first in place. We’ll start in the front yard….
This is a view of our front yard, looking southwest. Where is the lush green lawn in the semicircle and beyond? Why do those parts look nearly dead yet the little strip on the left (east) looks good? What happened??
Well, several things. First, the little strip which looks nice has quite a few of the old Champion sprinkler heads closely spaced for proper coverage. Second, the brown lawn outside the semicircle is a Darwinian experiment: we don’t know if we want to still have lawn there, and it was mostly St. Augustine, to which i am allergic. So, we are intentionally not irrigating that section, so it is not surprising that it looks bad.
The surprise may be the semicircle: it is being irrigated, and one would assume that if it is properly irrigated, it should look like the little strip which is green. Yes, it should. Here are some reasons it does not:
The K-Rain Dial-A-Nozzle seemed like a really good idea, especially for a person such as myself timid about making a mistake picking the one correct nozzle size for a normal rotary head. Well, with 5 of these heads in service since the 2002 part of the renovation (4 on the back lawn + one on the semicircle here in the front), i am prepared to state my opinion: they are inconsistent in performance, especially coverage pattern. One of them (in the back yard) seems very good; the others seem spotty, and in different ways. Some do better in close and others farther out. All are adjusted to one of the low angle nozzles and any which need them are using breakup screws, which does help even out the pattern slightly.
The better news in this picture is that the drip systems, feeding all the plants on the periphery, seem to be doing very well indeed… and saving gallons and gallons of water vs. spray heads.
