Summer watering schedule for cannas in Phoenix, Arizona
As you can see from this view behind the cannas, there is a 1/2-inch low-pressure *drip system* water line a few inches from the block wall. The water is sprayed out, very precisely, and at the bottom of the plants, through risers and sprayer heads. They are held firmly in place by the holders, which are pounded in with a hammer. Note that the wall never, ever, gets wet. The whole idea here is to deliver the water exactly where it's needed, and nowhere else.
I keep this area clear to allow access, and to check to be sure that everything is working correctly. I can tell by doing a visual whether a particular area is wet or dry, and the *wiener dog highway*, which is about a foot or so wide, along the block wall, always remains dry.
