Maintained green lawns are a trend that was imported here from the old English country estates and they didn't actually catch on in America
until the postwar era.
Now, I can understand if someone in Maryland, Virginia or Kentucky wants a lush green lawn.
It's not like you really need to do a lot of work to get it watered.
But the very idea that one has to install an underground SPRINKLER system in SoCal is the first hint you're on a fool's errand.
What do lawns offer anyway? Looks? SoCal isn't England and we're not living in some country manse.
And it's a desert. I can't even begin to imagine how much water we waste on effing GRASS, just so that we can pretend we live in
some grand estate in Europe with rolling green hills and lush foliage.
The appropriate landscape for SoCal is cactii, decorative rocks, hardy succulent desert plants and flowers, and stone.
