Sonoran Desert · Phoenix metro

Stop guessing how to water
your desert trees.

Most desert trees in the Phoenix metro die from overwatering, not drought. Answer 8 quick questions and get a month-aware watering plan tuned to your tree, soil, sun, and recent rain — built on Sonoran-specific guidelines, not generic landscape advice.

Sample result

Water every 14–30 days

Mesquite · Established · Spring · Full sun · Typical desert soil

  • Soak to 24–36″ at the drip line
  • Skip the next cycle if heavy rain
  • Don't water against the trunk

Why generic advice fails desert trees

A mesquite and a citrus tree have nothing in common when it comes to water. Same goes for July versus February. Our recommendation engine encodes both.

Month-aware, not 'seasonal'

Five Sonoran month-groups (winter, spring, dry heat, monsoon, fall) — because May and August aren't the same thing.

Stage-aware

Newly planted, establishing, young, and established trees each get a different schedule.

Symptom-aware

Yellow leaves on wet soil don't mean "water more." We catch overwatering, drainage, and compaction signals before they kill the tree.

How this guide is built

Field-informed, Sonoran-specific, honestly built.

Built by Treelation, an Arizona tree-care practice serving the Phoenix metro since 2012. The recommendation engine is grounded in nearly three decades of hands-on experience with trees, irrigation, and soil — and is being continually refined through field use, ongoing arborist study, and review against real desert-tree conditions.

Educational guidance for homeowners. Site-specific issues may still require an on-site assessment.

  • Sonoran-specific: built for desert conditions, not generic landscape rules.
  • Month-aware: May, July, and October are not the same watering month.
  • Symptom-aware: catches overwatering and drainage problems, not just thirst.
  • Always learning: currently studying for the ISA Certified Arborist exam and additional summer coursework in desert watering and rainwater harvesting.
  • Reviewed: the engine is being reviewed by working arborists ahead of and after launch.
