Hill Country Lawns Done Right
Last updated:

Austin Water is in Conservation Stage for 2026, and the schedule is stricter than a lot of homeowners realize. Whether your yard is in Zilker, Hyde Park, Mueller, Circle C, or out toward the suburbs, the same rules apply, and watering on the wrong day or in the wrong window can bring a fine. Here is exactly what is in effect, how to find your day, and a month-by-month plan to keep a Central Texas lawn healthy on very little water.
Your Austin watering schedule
Under Conservation Stage, how often you can water depends on the equipment you use:
- Automatic in-ground irrigation systems: one designated day per week, and only before 10 a.m. or after 7 p.m.
- Hose-end sprinklers and drip irrigation: up to two designated days per week, same hours.
- Hand-held watering and tree bubblers: allowed any time, no day or hour limit. In a Texas summer this is how you keep live oaks and beds alive when the lawn cannot be watered.
Your designated day is based on your address. Austin Water does not publish the full address-to-day map in its notices, so look yours up at austinwater.org under “Find Your Watering Day” and set your controller to match. The midday block matters: water applied between 10 a.m. and the evening loses a large share to evaporation before roots ever use it.
What the wrong day costs you
These restrictions are enforced, not suggested. Watering outside your assigned day or the allowed hours can trigger a violation, and repeat violations escalate. Beyond any penalty, running an inefficient system in the heat simply wastes money, because so much of a midday cycle evaporates. The households that pour the most onto thirsty turf are the ones paying the most for the least result.
New sod, seed, and plantings
Newly installed landscapes need more water to establish than the once-a-week rule allows. Hand-watering is permitted any time, which covers new trees, shrubs, and beds with a slow soak at the base. Austin Water also offers a variance process for new or replacement landscapes on an automatic system. If you are installing this season, apply through Austin Water for the establishment variance and time the project so the young plants are not fighting both the heat and the schedule.
2026 Austin lawn care calendar
Austin lawns are warm-season grasses, mostly St. Augustine and Bermuda, so the calendar follows their growth.
- Spring (Mar to May): as the lawn greens up, drop mowing to a clean first cut, apply a pre-emergent early to stop crabgrass, and fertilize only after full green-up. Check the irrigation system for broken heads before the heat arrives.
- Summer (Jun to Aug): peak heat and peak stress. Mow high (St. Augustine at 3.5 to 4 inches) to shade roots, water deep and infrequent on your assigned day, and scout for chinch bugs and grubs, which explode in the Central Texas heat.
- Fall (Sep to Nov): the recovery window. Fertilize to rebuild roots before dormancy, aerate compacted areas, and address any thin spots. This is also the best season for new installs, hardscape, and design work.
- Winter (Dec to Feb): the lawn goes largely dormant and needs little water. Use the cool months for planning, bed cleanup, tree work, and any renovation you want green by spring.
An Austin yard built for one-day watering
Following the schedule is the floor. The yards that stay healthy on one day a week are the ones designed for it. Cycle-and-soak is the most useful habit here: split each zone into two or three shorter runs so water absorbs into our tight, often caliche-heavy soils instead of running off. Swapping old spray heads for high-efficiency rotary nozzles, and moving beds to drip, cuts waste sharply. Converting the hardest-to-water strips to native and adapted plantings removes the thirstiest turf entirely, and Austin Water offers WaterWise rebates that can offset part of a conversion.
The bottom line for 2026
Know whether you are on the one-day (auto) or two-day (hose-end and drip) track, look up your assigned day, keep watering out of the midday window, lean on hand-watering to protect trees, and match your design to Central Texas. Do that and your lawn can look good all season without risking a violation.
If you would like a hand setting a controller to your legal day, fixing irrigation efficiency, or planning a lower-water yard, the Austin Pro Landscape Team works with these exact conditions every day.
