Short Answer: Under Stage 1 restrictions, most North Dallas cities allow watering twice per week on assigned days, between 6 p.m. and 10 a.m. Under Stage 2, watering drops to once per week. The smart schedule under either rule is the same: deep, infrequent cycles that put down a half inch of water per cycle, applied between 4 a.m. and 8 a.m. when restrictions allow, using cycle-and-soak on alkaline clay soils to prevent runoff. Bermuda survives Stage 2 fine. St. Augustine needs every legal drop, plus a soil moisture management plan that includes wetting agents, organic matter topdressing, and selective hand watering of high-stress areas where allowed. Pair the schedule with mowing at the upper height range, sharp blades, and accepting some summer dormancy. The lawns that come through Stage 2 looking the best are the ones whose owners used the rules strategically rather than fighting them.
If you have lived in Prosper, Celina, Frisco, Plano, or McKinney for more than two summers, you already know the rhythm. The reservoirs at Lavon and Lewisville drop through May. The city sends out the Stage 1 notice. Watering moves to twice a week. By July or August in most years we end up at Stage 2 or contemplating it, and the conversation at every backyard cookout in the neighborhood turns to whose lawn is holding up and whose is not.
We get the question every June across our service area. “Can I keep my St. Augustine alive on twice a week? Once a week?” The honest answer is yes, but only with the right schedule and the right cultural choices to back it up. Here is the playbook we use with North Dallas homeowners.
The Restriction Rules in Plain Language
Each city sets its own restriction stages, but the framework is similar across North Dallas. Stage 1 typically allows watering two days a week, with assigned days based on your address (odd-numbered addresses one set of days, even another), between specific hours (often 6 p.m. to 10 a.m.). Stage 2 typically drops to once a week, sometimes with shorter time windows. Hand watering and drip irrigation are usually permitted on any day, with restrictions removed or relaxed.
Check your city’s exact rules every spring. Prosper, Frisco, McKinney, Plano, Allen, and Celina all have slightly different specifics, and they update. Most cities post a current stage status on their website and send notifications when stages change. Penalties for violations escalate quickly, starting around $200 for a first offense in most North Dallas municipalities and rising into thousands for repeat violations.
The takeaway: the rule is not “less water.” The rule is “water on specific days, within specific hours.” Within that rule there is plenty of room to keep most of your lawn alive if you use the time you get well.
The Math: How Much Water Your Lawn Actually Needs
Bermuda and St. Augustine in North Dallas summer heat need roughly one to one and a quarter inches of water per week to stay actively growing. That number drops to around three quarters of an inch if you are willing to let the lawn ride through summer at slightly slower growth (which most professional turf managers in our climate would recommend anyway, since pushing summer growth in 105-degree heat invites disease and pest pressure).
Under Stage 1 restrictions (two days a week), you have two cycles to deliver roughly an inch of water. Each cycle needs to put down half an inch. Under Stage 2 (one day a week), one cycle delivers the whole week’s water, ideally three quarters to one inch in a single deep soaking.
To calibrate: set a tuna can or rain gauge in a representative section of your irrigation zones. Run the system for fifteen minutes and measure depth. Multiply to figure out how long each zone needs to run to deliver half an inch. Most rotary sprinklers in North Dallas need 20 to 40 minutes per zone to put down half an inch. Pop-up spray heads need 10 to 15 minutes. Drip irrigation is calculated by emitter flow rate.
Cycle and Soak: The Single Most Important Technique on Alkaline Clay
Collin and Denton County soils are heavy alkaline clay. Most of the North Dallas suburbs sit on Houston Black and Blackland Prairie soil series, which have high clay content, high pH (often 7.5 to 8.2), and a tendency to seal up at the surface when watered too fast. Pour half an inch of water on a baked North Texas clay surface in twenty minutes and most of it runs into the street. We see that every June.
Cycle and soak fixes the runoff problem within the restriction window. Instead of running each zone for forty minutes straight, run it for ten to fifteen minutes, let it sit thirty minutes for the surface to absorb, then run it another ten to fifteen minutes. Most modern irrigation controllers (Rachio, Hunter, Rain Bird) have a built-in cycle-and-soak function that handles the scheduling automatically. Older controllers can be programmed manually using two start times spaced an hour apart.
The result is night-and-day. A homeowner in Prosper who shifts from one long cycle to cycle-and-soak gets noticeably more usable water in the root zone, with no change in water bill or restriction compliance. We tell every customer this on first visit, and the customers who implement it tell us their lawns hold up dramatically better in July.
Time of Day: Use Every Legal Morning Hour You Can
Most North Dallas restriction rules allow watering during a window that includes both early evening (6 to 10 p.m.) and early morning (midnight to 10 a.m.). The smart play is morning, specifically 4 a.m. to 8 a.m., for several reasons.
Morning watering loses less to evaporation. North Dallas afternoon temperatures often hit 100 degrees with low humidity, and evening watering still puts moisture on the lawn going into a warm night, which feeds disease. Morning irrigation allows the canopy to dry within an hour of sunrise, which dramatically reduces brown patch on St. Augustine and dollar spot on Bermuda. Morning watering also coincides with the lowest wind, meaning sprinkler patterns deliver water where you intended rather than onto the neighbor’s driveway.
If your assigned days include both AM and PM windows, take the AM. If your city only allows evening, use the latest legal hour and the shortest cycle that delivers the water you need, which minimizes overnight wetness.
Stage 2 Strategy: Mowing Height, Wetting Agents, and Accepting Dormancy
Once a week is doable. Doable means the lawn stays alive and recoverable. It might not mean the lawn stays green and lush, especially for St. Augustine, which is the more water-demanding of our common species. The customers who navigate Stage 2 best in our region make three additional moves.
First, raise the mowing height to the upper end of the cultivar’s range. St. Augustine at 4 inches holds soil moisture dramatically better than St. Augustine at 2.5 inches. Bermuda at 1.5 inches outperforms Bermuda at 0.75 in dormancy resilience. Taller grass shades the soil, reduces evaporation, and develops deeper roots.
Second, apply a wetting agent. Soil surfactant products (Hydretain is the most common residential brand, Revolution and similar commercial products work too) help water penetrate sealed alkaline clay and increase the moisture available to grass roots. A May or early June application can effectively add 20 to 30 percent more usable moisture to whatever you put down. The cost is around $30 to $80 for a residential property, which is the cheapest yield improvement available under restrictions.
Third, accept some dormancy. Bermuda can go dormant (brown and crispy) during severe drought and recover fully when water returns. St. Augustine is less tolerant. If you have Bermuda and the restrictions go to Stage 2 plus extended heat, letting the lawn go semi-dormant for three or four weeks is fine. The lawn will green up in September.
Hand Watering and Drip: The Loopholes That Save High-Value Spots
Almost every North Dallas restriction stage allows hand watering with a handheld hose (with a shutoff nozzle) and drip irrigation on any day. That gives you a tool for saving the highest-stress sections of the lawn during Stage 2.
The hand-watering loophole is most useful for sections that bake hardest, the south-facing strip along the sidewalk, the area against a west-facing brick wall, or a slope where irrigation never quite covers. Twenty minutes with a hose, deep watering those specific zones an extra day or two a week, can keep otherwise-doomed sections alive.
For new sod laid recently, most cities provide a temporary exception that allows daily watering for two to four weeks after installation. If you have new sod going in summer, document the install date and confirm the exception process with your city in writing.
What Not to Do Under Restrictions
- Do not water on non-assigned days, even by hand if your city restricts that under Stage 2. Penalties are real and neighbors do report.
- Do not water during the prohibited daytime hours. Beyond the restriction violation, mid-day watering loses 30 to 50 percent of the water to evaporation in our heat.
- Do not fertilize heavily in summer under Stage 2. Fertilizer pushes growth the lawn cannot support without water. Wait until restrictions ease in fall.
- Do not aerate or dethatch in summer. Both create open soil that loses moisture faster.
- Do not over-mow. Reduce mowing frequency along with watering frequency. Bermuda mowed every ten days under Stage 2 holds up better than Bermuda mowed every five days.
What to Do Next
If your North Dallas lawn is going into restrictions and you want a watering schedule calibrated to your specific irrigation system, soil, grass type, and city rules, we can walk the property and set it up. Twenty minutes of calibration saves water, reduces your bill, and protects the lawn through summer.
