Arizona native plants and cactus — what they are, and how not to kill them.
Natives should be the easiest plants in a Phoenix landscape. They evolved here. But most native installs die within 24 months — because they get planted like ornamentals: deep, amended, and over-watered. Here's the plant palette and the correct care.
The core Sonoran native palette
- Trees: palo verde (foothill, blue), mesquite (velvet, honey), ironwood, desert willow.
- Cactus: saguaro, prickly pear (Opuntia), cholla (jumping, staghorn), barrel, hedgehog.
- Succulents: agave (americana, parryi, weberi, victoriae-reginae), yucca, hesperaloe (red, yellow).
- Shrubs: brittlebush, creosote, jojoba, fairy duster, chuparosa, damianita.
- Perennials: globe mallow, desert marigold, penstemon (Parry's, firecracker), blackfoot daisy.
- Groundcover: desert zinnia, verbena, trailing indigo bush.
Planting spec (all natives)
- Plant October–April. Never May–August.
- Dig hole 2× width of root ball, same depth or 1" shallower.
- Lean planting mix — 20% max compost, or none at all for pure cactus.
- Root crown must sit 1" above final grade.
- Backfill and firm; water in once, then walk away.
- Mulch with decomposed granite, not bark. Keep granite 4" off the trunk.
Water schedule by year
- Year 1: deep water every 10–14 days summer, 3–4 weeks winter.
- Year 2: every 3–4 weeks summer, monthly winter.
- Year 3+: monthly summer, natural rainfall winter (unless drought).
- Separate irrigation zone from ornamentals — never share with shrubs on 7-day cycles.
Saguaro-specific rules
- Only nursery-grown or salvaged (with tag). Never wild-collected.
- Plant at exact nursery depth — mark and preserve north-facing side.
- Full stake support for 12–18 months on any saguaro over 4 ft.
- One water at planting, then nothing for 12 months in most cases.
- Winter freeze: mature saguaros tolerate 15°F. Wrap tops of young saguaros below 25°F.
Frost protection
- Mature Sonoran natives — no protection needed above 15°F.
- Marginal species (golden barrel, cardon, blue agave) — frost cloth below 28°F.
- Never plastic. Frost cloth or old sheets, removed by mid-morning.
What AE builds
- Native-palette landscape designs matched to full-sun, part-sun, and shade microzones.
- Saguaro relocation and placement with permit coordination.
- Separate low-water irrigation valve for the native zone.
- Decomposed-granite mulch and edge detail matched to the design.

AE designs and installs Sonoran-native landscapes with the correct irrigation, spacing, and long-term care plan. One accountable team from concept through year-one establishment.
Start My Project PlanWhy this is an investment, not a cost.
An AE backyard is engineered to add daily livability and long-term home value. We publish honest ranges and build to code with a licensed and bonded Arizona crew. AE provides project-specific workmanship and manufacturer-warranty information in the signed agreement. Website summaries are for planning only.

Most Arizona contracting work valued at $1,000 or more — or requiring a permit — must be performed by a properly licensed contractor, subject to statutory exemptions. Verify the legal entity, license status, and classification with the Arizona Registrar of Contractors.
- Real ranges, itemized scope. You see materials, finishes, equipment models, and a line-item budget before you sign — not a one-line "pool — $90,000."
