Most irrigation problems we see aren't broken parts. They're systems that water every plant the same way: sprayers on shrubs, lawns on the same timer as trees, and heads that hit the sidewalk more than the soil.
Drip irrigation puts water directly at the roots of shrubs, perennials, and trees, with almost nothing lost to wind or evaporation. It's the right choice for planting beds, slopes, and drought-tolerant gardens, and it keeps foliage dry, which cuts down on disease.
Sprinklers and rotors still make sense for natural lawns, where you need even coverage across a wide area. The key is putting lawns and beds on separate zones so each gets what it needs and nothing more.
Tie it together with a weather-based smart controller and the system adjusts itself after rain and through the seasons. A quick audit of an existing system, checking pressure, coverage, and leaks, often pays for itself within a single summer.
