North Texas Watering Restrictions: Keep Your Lawn Green Legally

Most cities across the Dallas-Fort Worth metroplex limit outdoor watering, commonly to twice a week on assigned days, with no watering during midday hours. Restrictions vary by city and can tighten during drought stages, so your first step is always checking your own city's current schedule. But here's the good news most homeowners don't realize: a lawn watered correctly twice a week is usually healthier than one watered a little every day. The restrictions aren't the enemy. Bad watering habits are.

‍

Why Twice a Week Is Actually Enough

Shallow, frequent watering trains grass roots to stay near the surface, where they cook in July. Deep, infrequent watering pushes roots down into the soil where moisture lasts longer between cycles. Bermuda, Zoysia, and St. Augustine, the dominant turf grasses in North Texas, all respond well to deep watering once establishment is behind them. The goal on your two allowed days is to get water deep into the root zone without runoff.

The Cycle-and-Soak Method for Clay Soil

North Texas clay absorbs water slowly. Run a zone for 20 straight minutes and much of that water sheets off into the street. The fix is cycle-and-soak: split each zone's runtime into two or three shorter cycles with 30 to 60 minutes between them, letting each round soak in before the next begins. Same total water, dramatically better absorption, and zero waste running down the curb. That matters, because letting water run into the street can itself violate local watering rules.

Water Early, Not at Night

The best watering window is early morning, finishing around sunrise. Midday watering loses a significant share to evaporation, and it is prohibited during summer months in most DFW cities anyway. Late-evening watering leaves grass wet overnight, which invites fungal disease, a real problem for St. Augustine in humid stretches.

Let Your Controller Do the Compliance Work

Modern smart controllers make restrictions nearly effortless. Set your city's allowed days once, and the controller handles scheduling, splits cycles automatically, and skips runs after rainfall. Texas law also requires rain and freeze sensors on newer automatic systems, and cities reward efficient setups because they reduce demand. If your controller predates smartphones, upgrading is one of the highest-return improvements you can make, both for the water bill and for staying compliant without thinking about it.

Fix the Leaks First

None of this matters if your system is bleeding water. A single broken head or weeping valve can waste more water than your entire legal watering schedule uses. If you're seeing dry spots despite watering on schedule, the problem is usually coverage or pressure, not the restrictions. A zone-by-zone system audit finds the heads that drifted out of alignment, the nozzles that clogged, and the leaks hiding underground.

A Greener Lawn on Less Water

We've been designing and tuning irrigation systems in North Texas for more than 35 years, through every drought stage the region has seen. A properly designed system with smart scheduling keeps lawns green on two days a week: legally, and usually with a lower water bill than the neighbor running a leaky system four mornings at a time.
