*shriek!* Some postings on social media gardening sites drive me crazy!
I just read a post on a Facebook gardening group from a newbie who has planted a big green lawn next to his new home in Arizona. It was, he said, like the one he had Back East. He proudly included photos and thanked other members of the group for all the advice they gave to him. He “couldn’t have done it without them”.
What??!!?
I wonder who told him that a grassy green British lawn was a good idea in a hot, dry climate? That it was a good idea in a land where water has to be imported hundreds of miles across a desert so he can turn a faucet and spill that water on to desert soil where it soaks in an inch or two and/or evaporates almost instantly.
Blame those green lawns on the Brits
Yes. Neatly trimmed green lawns originated in the rainy, damp British Isles. They are not common around private homes in Spain or Italy or Germany or elsewhere in the E.U. or most of the world. And even in the U.K. lawns are a relatively recent innovation that had something to do with wealthy landowners raising sheep or impressing the neighbors or something. Sadly, the lawn idea took hold and jumped across the Atlantic where it spread across the continent–even into Southwest desert communities.
American home builders also are to blame for the U.S. lawn obsession because they planted lawns in massive housing developments particularly after WWII because turf grass in the front yard is easy, cheap and fast landscaping.
Serious drought…really serious
I wonder if that newbie lawn guy, and other well-meaning, but poorly informed, participants in that group, realize how serious the drought conditions are in the U.S. Southwest as the U.S. Drought Monitor shows.
And how fast water tables in towns across the Southwest are falling as local water districts–the ones not relying on Colorado River water–pump more and more local ground water to new housing developments where new homeowners are planting wasteful lawns.
And I wonder if they realize that ground water isn’t being replaced in reservoirs and rivers with rain falling from the sky. The soil just gets drier and drier. The local wells have to go deeper and deeper. And choosing to plant a lawn becomes more and more absurd.
Local government officials are trying to handle current and future water usage. Efforts to slow down and re-allocate usage of water imported from the Colorado River show up in things like golf courses closing or being converted to dry landscaping and towns passing laws to ban lawns in front yards.
But there are other choices.
Before I show you some attractive lawn-free gardens for hot dry climates I’d like to suggest that if your heart is really set on the look of a lawn consider planting Buffalo Grass (Buchloe dactyloides) an Arizona native grass that many are planting as turf. Originally known as the grass that American buffaloes (bisons) grazed on, it grows green in summer, dies back to brown in the Fall and needs no irrigation and almost no mowing after it is established. [Note: This is not the invasive Buffelgrass (Pennisetum ciliare), an African native that is overwhelming plants in the Sonoran Desert. ]
Beautiful replacements for grassy lawns
So here are a few examples of front yards that are lawn-free.
A front yard filled with blooming perennials including kangaroo paw, sea lavender, rosemary and flat grey dymondia groundcover. This garden is located in Pasadena which gets about 17 inches of rain each year.
A desert-style garden in Springtime when the aloes and other plants are in bloom. This garden is located in Tucson which receives about 12 inches of rainfall a year.
These homeowners added berms, small “hills”, to their previously flat front lawn and planted drought-tolerant shrubs and trees that need almost no maintenance. Goodbye lawnmower! Berms need to be carefully designed to channel rainfall away from the house foundation.
This landscaped garden includes a dry creek bed as an ornamental feature surrounded by agaves and blue-gray fescue grass and taller green deer grass. As with adding berms in a garden, adding a dry creek bed has potential problems. Dry creek beds are not always dry and should be designed so rain water flows away from a home’s foundation.
I think of this front yard with its large decomposed granite space as a Mexican Garden because it reminds me of plazas and courtyards I’ve seen in Mexico. The “bare ground” decomposed granite suppresses weeds and is surrounded by drought tolerant plants that bloom seasonally. Zero maintenance and it requires only the water from the sky.
I was also going to write about silly social media posts praising decorative backyard ponds, but I have ranted enough for today. Those weird backyard ponds are as wasteful as grassy green front lawns in hot dry climates. If you have one, convert it to a flower fountain with plants on each level.
A postscript: there are now over 6,000 Little Free Plant Stands in Arizona! Vastly more than when I wrote about them back in March.
