There’s a well defined architectural vocabulary house flippers use in our neighborhood. Flippers buy a crumbling 1920s bungalow, paint the front door orange, add a horizontal fence, redo the interior in a Home Depot meets Dwell Magazine style and then turn around and sell it for a million bucks.
When house flippers tackle a yard they tend towards the “low-maintenance” landscape (in quotes because there’s no such thing as a low-maintenance garden). One of the favorite tools in the flipper landscaping toolbox is decomposed granite (DG) used as a mulch. Put some plastic landscape fabric down (blocks rainwater in our climate, fyi) and top that plastic with DG. They then punch some holes in the DG/plastic and pop in succulents and maybe a rosemary bush or two. By the time the yard becomes a sad, desertified tangle of unhappy succulents and crabgrass, the flippers are long gone.
I’ve got a big issue with DG as mulch. In order for DG to look good, it’s got to be compacted and soil compaction is really bad for plants, including hardy natives and succulents. It stifles the life of the soil, and does not build new soil. And eventually, the plastic will fail, and the weeds will come through (some come through even when the plastic is new), and whoever is left holding the bag a couple of years down the road will be pulling decaying bits of plastic out of their garden for evermore.
What’s a better approach? Wood chips. Pile it on thick. Skip the plastic liner. Eventually your new plantings will cover any bare areas if you space them correctly. It looks good, and the mulch breaks down and turns into soil. You will still need to weed but that’s called gardening. Save the DG for walkways. Or use mulch on your walkways too. Mulch is free or low cost. Just ask your local arborist to drop off a load.
