Landscapes should be watered regularly; and watering is mandatory for newly installed landscapes. There is nothing more frustrating than installing new plants and lawns only to see them suffer, or worse, die due to lack of moisture.
To establish properly, new lawns and plants require proper watering. And when the owners take the time to water everything should work out well.
Consider the picture below. The lawn and cedar hedge (Thuja occidentalis) are new; when I first visited this unit, there was no lawn, just two stumps. That was last year.
I'm very happy with the way things look.
