Arlington TX Odd-Even Watering Schedule: How to Stay Compliant and Keep Grass Alive

Watering restrictions in Arlington, Texas are not optional — and during drought conditions or Stage 2 declarations, the fines for violations are real. But the frustration many homeowners feel is that the odd-even schedule feels designed to hurt their lawn, not help it. In the middle of a DFW July, being told you can only water two or three days a week sounds like a sentence to a brown lawn. It doesn’t have to be. With the right system settings, you can stay fully compliant with Arlington’s watering rules and still keep Bermuda grass healthy all summer.

How Arlington’s Odd-Even System Works

Arlington’s water conservation ordinance divides outdoor irrigation into two groups based on address number. Odd-numbered addresses water on Tuesdays, Thursdays, and Saturdays. Even-numbered addresses water on Wednesdays, Fridays, and Sundays. No residential outdoor irrigation is permitted on Mondays. The allowed time window is before 10 a.m. or after 6 p.m. — a restriction designed to minimize evaporation losses during peak daytime heat.

During declared drought stages — which have become increasingly common in North Texas — restrictions may tighten. Stage 1 typically limits irrigation to two days per week. Stage 2 moves to one day per week with additional restrictions. Stage 3 often prohibits all outdoor irrigation. Following the current stage level is the homeowner’s responsibility; the City of Arlington does enforce these rules with fines ranging from $50 to $2,000 per violation.

The Early Morning Window Is Your Best Friend

Of the two allowed windows, early morning is significantly better for your lawn. Watering before 10 a.m. — specifically between 4 and 8 a.m. — gives the soil maximum absorption time before heat drives evaporation. Bermuda grass blades that get wet at 5 a.m. are dry by 8 a.m. as temperatures climb, which dramatically reduces disease pressure from fungal issues like brown patch and gray leaf spot. Evening watering, while technically allowed after 6 p.m., leaves foliage wet overnight — a prime condition for fungal disease spread through DFW’s warm, humid summer nights.

Program your controller to start the earliest zone between 4 and 5 a.m. on your permitted days. If you have six zones averaging 20 minutes each, you’re done by 6:00–6:30 a.m. — well inside the window and with plenty of drying time before the heat arrives.

Making Two or Three Days Per Week Work for Bermuda

Bermuda grass in North Texas typically needs 1 to 1.5 inches of water per week during July and August. On a three-day schedule, that means delivering approximately 0.35 to 0.5 inches per irrigation session. On a two-day schedule, each session needs to deliver 0.5 to 0.75 inches. Here’s how to hit those targets without violating the daily time restriction:

• Know your precipitation rate. The average residential spray head delivers about 1.5 inches per hour. Rotor heads typically deliver 0.4–0.6 inches per hour. Knowing your rate tells you exactly how long to run each zone to hit target depth.
• Use cycle-and-soak on heavy clay zones. If your clay soil can’t absorb 0.5 inches in a single run without runoff, split that run into two shorter cycles 45–60 minutes apart. Both cycles happen within the same allowed window and the soil absorbs far more of what you apply.
• Eliminate non-essential zones. Median strips, ornamental beds, and hardscape-adjacent areas may not need the same frequency as lawn zones. Adjust each zone independently so water goes where the lawn needs it most.
• Adjust for rain. Every modern controller has a rain sensor port. If yours doesn’t have an active rain sensor, install one ($25–60) — or better, a smart controller that consults local weather data. Skipping a watering day after 0.5 inches of rainfall is not just water conservation, it’s what keeps Bermuda from developing fungal disease from overwatering.

Watering Restrictions and Lawn Treatment Timing

One aspect of watering restrictions that trips up many homeowners is coordinating irrigation with lawn care treatments. Most fertilizer and weed control applications require watering within 24–48 hours of application to activate properly. Granular pre-emergent, for example, needs water to drive it into the soil where it creates a barrier. If your permitted watering day falls three days after an application, the product may not perform as designed. The practical solution is to schedule lawn treatments to fall the day before or the day of a permitted watering cycle. Professional lawn care programs account for this automatically when scheduling treatment visits for Arlington customers.

Common Compliance Mistakes to Avoid

• Running systems on restricted days: A controller set to “every other day” or “every 3 days” may drift into a non-permitted day over the season as you adjust run times. Use the specific days-of-week setting on your controller, not interval mode.
• Watering during the 10 a.m.–6 p.m. blackout period: A 4 a.m. start time that runs zones into morning is fine. A 9 a.m. start time that runs long zones into 10:30 a.m. is a violation. Calculate total runtime and ensure the last zone finishes before 10 a.m.
• Irrigating within 48 hours after rain of 0.5 inches or more: Under Stage 1 restrictions, watering after significant rainfall is prohibited regardless of your permitted day. A rain sensor or smart controller handles this automatically.
• Not updating the schedule when restrictions change: Stage levels change with drought conditions. Set up the City of Arlington’s water conservation alerts so you know immediately when a stage change is declared.

What Happens When Bermuda Does Go Dormant

Even with perfect compliance, a Stage 2 or Stage 3 restriction during an extreme drought may push Bermuda grass into dormancy. This is not the same as death. Bermuda has deep root systems that can survive extended dormancy if the crowns stay alive. In most DFW drought situations, Bermuda that goes dormant in August recovers fully once watering resumes and fall temperatures moderate. The goal during restriction periods is to keep the root zone from completely desiccating, not to maintain full color.

Stay Compliant, Stay Green

The homeowners who keep the best-looking lawns in Arlington during drought summers are not breaking the rules — they’re just smarter about how they use their permitted days. Early morning watering, proper runtime calibration, cycle-and-soak for clay soil, and coordinating treatments with watering windows all add up to a lawn that looks dramatically better than its neighbors on the same restrictions.
