By mid-August the brick and blacktop of Union City hold the day's heat long past dark, and any grass that isn't watered gives up fast. FJ Gardener & Irrigation Water Systems takes the early hour instead — heads checked and zones cycling while the streets are still gray, so the water goes into the soil rather than up into the air. Sprinkler lines get installed, adjusted, repaired, started in spring and shut down before the freeze; lawns and beds get mowed, trimmed and kept between visits. Up near the old reservoir grounds the land rolls just enough to send water somewhere you never asked it to go, which is exactly why the tuning matters. There is a real satisfaction in a system that clicks on quietly at five and leaves a green yard standing in a city of stone.
