October in Palm Springs: When Desert Planting Season Really Begins
October has arrived in Palm Springs. Fall, apparently, has not. That matters if you're thinking about installing a new landscape.
October traditionally signals the beginning of our prime desert planting season. But increasingly, the calendar and the weather aren't quite in agreement. Early October can still look—and feel—remarkably like summer. So rather than asking, Is it October yet?, there's a better question
Is it actually cool enough to plant?
Watch the thermometer, not the calendar
For most landscape trees, shrubs, grasses, perennials and succulents, fall planting can begin once daytime temperatures are consistently below 100°F and cooler nights have returned. Ideally, we like to see that change settle in rather than react to the first brief break in the heat.
Warm soil encourages root development. Cooler air reduces stress on newly installed plants. Instead of simply surviving the heat, plants can begin establishing the root systems they'll need for next summer.
In Palm Springs and the Coachella Valley, that increasingly may mean waiting beyond the traditional start of October. And that's fine.
Planting season isn't a four-week window. It's a change in conditions.
Once that change occurs, our prime planting season extends through the cooler fall and winter months and into spring, with adjustments for individual plants and their particular sensitivities.
There is no advantage to rushing it. A landscape installed a little later under favorable conditions may establish far more successfully than one planted simply because the calendar says October.
Why fall planting matters
In many climates, spring is the obvious time to plant. In the Coachella Valley, fall offers an important advantage: plants installed in fall have months to establish before they're asked to endure their first Palm Springs summer.
By spring, a properly planted tree, shrub or perennial isn't starting from zero. It has already begun adapting to its soil, irrigation and microclimate.
When triple-digit temperatures eventually return, you're dealing with an establishing garden rather than a collection of recently transplanted nursery plants.
One garden. Different calendars.
Not every plant wants exactly the same conditions. Palms, cacti, succulents, desert-adapted trees, Mediterranean shrubs and more tender subtropical plants don't necessarily follow the same schedule. Some heat-loving plants can be installed outside the traditional fall window. More cold-sensitive material may be better held until spring.
Exposure matters, too.
A plant in an east-facing courtyard protected from afternoon sun faces very different conditions from the same plant against a west-facing wall surrounded by stone and reflected heat.
Plant selection, exposure and timing have to be considered together.
That's one reason we don't design desert landscapes from plant lists.
Start with structure
When people imagine a lush garden, they often imagine abundance: more plants, more flowers, more color. But compelling desert gardens aren't necessarily about more. They're about placing the right things with intention.
We begin with structure.
A sculptural tree can establish an entire composition. A palm creates a dramatic vertical counterpoint to a low horizontal house. An agave, yucca or desert spoon can occupy an important sightline almost as a piece of sculpture.
Boulders aren't decorations scattered among plants. They can create geology—ridges, outcroppings and changes in grade that make a landscape feel as though it belongs to the land.
Then come the intermediate layers: shrubs, grasses, succulents and groundcovers that connect the larger gestures.
The objective isn't to fill every available space. It's to decide where the eye should go next.
“Design is the choreography of attention.”

Revealed in layers
We also design landscapes from the inside of the house outward. What do you see through the living room glass? What catches your eye from the kitchen? What happens as you approach the front door? And what is deliberately not revealed until you turn a corner?
A specimen tree might frame a mountain rather than obscure it. A palm trunk can divide a broad view into two compositions. A boulder ridge can partially conceal what lies beyond.
A successful garden doesn't announce itself all at once. It unfolds.
Revealed in layers.
Beyond the usual desert plant list
Water-conscious landscaping no longer means choosing among the same dozen plants repeated throughout the Coachella Valley. The palette is much richer than that.
Think about plants according to the role they play in the composition.
For architectural structure, desert spoon (Dasylirion), Yucca rostrata, Mexican fence post cactus and carefully selected agaves provide powerful sculptural forms.
For a softer middle layer, deer grass, selected muhly grasses and Lomandra introduce movement and contrast against more rigid desert forms.
For low spreading masses, Acacia redolens, trailing rosemary and other low shrubs can knit a composition together and eliminate the familiar look of individual plants floating in gravel.
And with trees, begin with the job rather than the species.
Does the tree need to shade an outdoor room? Frame a mountain? Screen a neighboring property? Create filtered canopy? Become an architectural marker visible from inside the house?
Then think about when you'll actually be here to enjoy it. A deciduous tree such as desert willow (Chilopsis linearis) can be spectacular in summer, covered in pink-to-purple flowers—but a seasonal Palm Springs resident may experience it primarily as a bare tree in winter. An evergreen may be a much better choice.
Maintenance matters, too. Some beautiful trees drop flowers, leaves, seedpods or fruit. That's very different in an open planting area than it is beside a swimming pool, walkway or outdoor dining space.
The right tree isn't simply one that thrives in the desert. It's one that works for the place, the season and the way you live.
Those questions lead to much more interesting choices than a generic list of “desert trees.”
Beyond the gravel field
There's a familiar desert-landscape vocabulary throughout Palm Springs: broad expanses of gravel punctuated by individual specimen plants. It's practical and water-conscious, but when every plant becomes an isolated object, the result can feel austere—sometimes more like a display than a garden.
We take a different approach.
The spaces between the specimens matter just as much as the specimens themselves.
Low groundcovers and spreading plants can move through a composition, connecting trees, agaves, grasses and stone into something that feels continuous and settled. They soften the transition between architecture and landscape and create depth without sacrificing the openness that makes a desert garden feel like the desert.
The ground itself becomes part of the design. Gravel and decomposed granite can shift in texture and scale. Cobble can suggest a wash. Boulders can emerge from planted areas rather than sitting on top of them. Subtle changes in grade can create landforms that give the garden a sense of having evolved rather than simply been installed.
None of this means covering every inch of ground. A desert landscape needs openness and breathing room.
But open space and empty space aren't the same thing.
When groundcover, stone, landform and specimen plants begin to relate to one another, the landscape stops feeling like a collection of objects placed in gravel. It begins to feel like it belongs.
Prepare now. Plant when the weather says go.
If temperatures are still too high, early October isn't wasted time. It's the time to finalize the design, prepare irrigation, address drainage, remove unwanted material, shape landforms, source specimen plants and boulders, and get the site ready.
Then, when the seasonal change has truly arrived, planting can begin.
The goal isn't to get plants into the ground as quickly as possible. It's to give them the strongest possible beginning—and enough time to establish before next summer asks them to prove themselves.
The calendar can tell us it's fall. The desert gets the final word.
