Newer isn’t always better

Notice how the trees are planted in the 17th-century Patio de Los Naranjos in Cordoba, Spain – in basins and connected by way of channels. No overhead emitters; no automatic sprinkler system. Just plants planted slightly sunken so that water can percolate straight down to the roots of the trees, drawing the roots down with it.

Many a landscape professional has looked on in horror when we have proposed or used this technique in our landscapes; and yet, here it is, time-worn and tested, the trees clearly thriving and growing well.

We need to start rethinking our planting practices and the notion that a landscape must have an irrigation system of emitters and lines and tubing in order to survive. The Patio de los Naranjos is yet more evidence of why this just isn’t so.
