Or at least with a little skill, they are!
Someone once summarized my design philosophy as “inspired by nature (desert)”. Here behind an unfulfilled project in the Mojave Desert outside Las Vegas: rock cover of various sizes, thin plant cover.
Desert pavement is the term for the ground surface in many shrub desert communities, and it is a great model for the aesthetic and function of gravel mulch in the arid-region garden.
After all, desert pavement in the wild serves as mulch.
The owner had their contractor do this on one of my designs. They tried, but the larger rocks need to have been impressed, or filled in between using the overall, smaller gravel mulch, to avoid looking contrived. Almost!
I specified this at a school design nearby, and it worked: 50 percent 3/8″ gravel mulch and 50 percent 3/4″ gravel mulch.
The architect didn’t get it, didn’t try, and he’s from El Paso. One cannot miss seeing this very same effect on the groundplane, on any hike or travel into our area’s creosote bush scrub. And an architect, who has more design savvy.
If some 2-4″ rock had been added to the mulch mix, his approval might have been even less. I tried, but easy isn’t so easy. People are the main limit, not reality.
Tree stakes…do you really think they need to remain after the first year, let alone 9 years later, with 4-6″ caliper trunks and obviously quite establish and sturdy?
Nor do I!
Disagreeing and not removing the stakes will not prove anyone right; it will girdle and damage the tree, possibly killing it.
