In Arizona, drip irrigation waters trees, shrubs and cactus; sprinklers are for grass. Most yards that convert from lawn to desert landscaping switch the old sprinkler zones to drip.
| Drip irrigation | Sprinklers | |
|---|---|---|
| Best for | Trees, shrubs, cactus, pots, beds | Grass lawns |
| How it waters | Slow, deep watering at the roots | Sprays the surface of the whole area |
| Typical run time | 2 hours or more; 2–6 hours is common | Short cycles |
| Common problems | Clogged emitters (hard water), blown fittings (high pressure) | Overspray onto walls and pavement, runoff |
Why drip fits desert plants
Most desert plants die from watering that is too shallow and too frequent. Drip lets you water deep and less often: about 1 foot deep for groundcovers and cactus, 2 feet for shrubs and 3 feet for trees (desert watering guide).
Keep a drip system healthy
Add a filter and pressure regulator on every zone, put emitters at the edge of the canopy, and change the controller with the seasons. Some cities offer smart controller rebates (rebates by city). Parts and kits: best drip irrigation systems for Arizona.
