Most Arizona homeowners replacing grass end up choosing between decorative rock and artificial turf, or a mix of both. Here's how they compare on cost, heat, water and upkeep, using the Phoenix-area prices from our rock guide and turf cost guide.
| Decorative rock | Artificial turf | |
|---|---|---|
| Installed cost | About $0.85–$1.60 per sq ft | About $8–$16 per sq ft |
| 500 sq ft yard | About $425–$800 | About $4,000–$8,000 |
| Water | None (plants on drip still need water) | None, but an occasional rinse |
| Summer heat | Hot in full sun, but shade trees and plants help | Can get hotter than asphalt in direct sun |
| Upkeep | Some weeding; top up every few years | Brushing, rinsing, topping up infill |
| Lifespan | Many years | About 15–25 years for quality turf |
| Best for | Front yards, side yards, low-water desert designs | Kids' and dog play areas, putting greens, a green look |
Prices are Phoenix-area ranges from our guides (checked Nov 2026), before tax. Rock prices are installed; buying and spreading it yourself costs less. Turf ranges depend heavily on base prep and product.
Cost: rock wins by a wide margin
Installed rock usually costs a small fraction of turf. Turf's price comes from the excavation, compacted base, product and infill. If budget is the main concern, rock with a few desert plants and drip irrigation goes much further. Check whether your city offers a grass removal rebate before you start; many rebates have rules about what can replace the grass.
Heat: plan for shade either way
Both get hot in July. Turf is the bigger concern for bare feet and paws: an Arizona State University study found artificial turf hotter than asphalt for most of a 114°F day. If you choose turf, put play areas where they get afternoon shade and ask about lighter or cooling products. Rock yards stay more comfortable with shade trees and plants mixed in.
Water and upkeep
Neither needs regular watering, which is the main reason Arizona homeowners switch. Rock needs occasional weeding (a pre-emergent helps) and a top-up every few years as it settles. Turf needs brushing, rinsing (especially with dogs) and occasional infill. Old grass must be killed first in both cases, or Bermuda will come back through.
A common answer: both
Many Arizona yards use rock for most of the area and a small patch of turf where kids or dogs play. That keeps the cost down while still giving you a soft, green spot.
