Xeriscaping in San Antonio makes sense right now. SAWS moved customers back to Stage 3 watering rules in September 2026, which means sprinklers run once a week. SAWS also runs some of the most practical landscape incentives in Texas. As of September 2026, SAWS WaterSaver Landscape Coupons are worth $150 each for fall (up to four per application window), its Outdoor Living rebate pays $300–$1,000, and its irrigation-removal rebate pays up to $5,000 (GardenStyleSA). The city sits in USDA Zone 9a with about 32 inches of rain a year that arrives unevenly. A San Antonio yard has to handle 100°F droughts, flash floods and the occasional hard freeze.
San Antonio growing conditions
| Factor | San Antonio | Source |
|---|---|---|
| USDA hardiness zone (2023 map) | 9a across the city (78205, 78258); 8b toward Helotes (78015) and the Hill Country edge | USDA |
| Annual precipitation | 32.38 inches | NOAA 1991–2020 normals |
| Median last spring frost | February 26 | NOAA |
| Median first fall frost | November 28 | NOAA |
| Soils | Shallow, rocky soil over limestone on the north side; heavy black clay to the south and east | Local observation |
- Edwards Aquifer levels drive the rules. SAWS moves between drought stages based on the aquifer level, so plan for once-a-week watering as the normal case, not the exception.
- North side versus south side. Stone Oak and the Hill Country edge have thin soil over limestone. Plant in berms and raised beds. South and east clays hold water, so drainage matters in wet spells.
- Freezes are rare but serious. Choose plants hardy to zone 8 for anything you can't afford to lose.

| WaterSaver Landscape Coupon | $150 per Fall 2026 coupon ($125 for Spring 2027) | 4 coupons per window | Remove at least 200 sq ft of grass per coupon; 15 approved plants; no irrigation in the new bed | Coupon |

The fall coupon deadline is close. Fall 2026 applications close October 15, 2026. Coupons must be redeemed at a participating nursery by November 1, and final photos are due November 15. Apply with a photo of the area before you remove anything, and wait for the approval email, which SAWS says arrives within two weeks. The spring 2027 window runs March 1–April 30.
The coupon and the irrigation rebate can be combined when irrigation valves are removed. SAWS says customers with irrigation systems use "70 percent more water on average in the summer and 50 percent more annually" than customers without them, which is why it pays so much to remove sprinklers. Rebates of $2,000 or more in a calendar year require an IRS W-9.
Watering rules: Stage 3
SAWS announced on September 21, 2026 that customers were returning to Stage 3. Under Stage 3 (SAWS):
- Sprinklers, irrigation systems and soaker hoses: once a week on your address-assigned day, only 5–10 a.m. and 9 p.m.–midnight. There's no watering on weekends.
- Drip irrigation and tree bubblers: Mondays and Fridays, during the same hours.
- Hand-held hose: any time, any day.
A new bed planted with a WaterSaver coupon has no permanent irrigation by design. Water it by hand while it gets established, which is allowed any day.
HOA rules: Texas protects drought-resistant yards
Under Texas Property Code §202.007, an HOA may not prohibit or restrict "drought-resistant landscaping or water-conserving natural turf," drip irrigation, rain barrels or composting. HOAs can still regulate "the installation or use of gravel, rocks, or cacti" and yard maintenance (Tex. Prop. Code §202.007). A planted native bed is well protected. A yard of mostly rock can still be regulated.
The South Texas plant palette
Shrubs: cenizo (Texas sage), esperanza (yellow bell flowers all summer), agarita, dwarf yaupon, and pride of Barbados where you can protect it from freezes.
Perennials: autumn sage (Salvia greggii), blackfoot daisy, damianita, mealy blue sage, lantana (trailing natives), zexmenia and rock rose (Pavonia). Blanket flower and gaura fill gaps.
Grasses: Gulf muhly, Lindheimer's muhly, sideoats grama, little bluestem, and inland sea oats for dry shade.
Trees: live oak, Texas mountain laurel (purple flowers in March), desert willow and anacua. See low-water trees.
Accents: red yucca, soft-leaf yucca, agaves and spineless prickly pear.
The WaterSaver coupon requires plants from SAWS's approved list, so choose from it first. Texas A&M AgriLife's Earth-Kind program has more research-based picks.
Design notes
- Think in 200 sq ft modules. Each coupon covers one 200 sq ft bed of 15 plants. Four coupons convert 800 sq ft a season.
- Replace turf with a patio where people actually walk, and use the Outdoor Living rebate. Use pervious stone and pavers (no mortar or concrete).
- Add shade trees first for summer comfort.
- Plan for heavy rain. Mulched beds, rain gardens and a dry creek bed slow runoff during storms.
From our installs: Fall is San Antonio's best planting season. The median first frost isn't until late November, so beds planted in October get weeks of root growth and a full spring before summer heat. That's also why the fall coupon is worth more.
Getting started before October 15
- Pick a sunny 200 sq ft patch of lawn and photograph it (existing beds don't qualify).
- Apply for the fall coupon with the photo, and wait for the approval email.
- Remove the grass and any sprinkler heads or drip lines in the bed area (lawn removal methods).
- Redeem the coupon for 15 approved plants at a participating nursery by November 1, and plant them in one contiguous bed.
- Mulch, hand-water through establishment, and send final photos by November 15. If you're removing a whole irrigation system, book the SAWS consultation first so you can claim that rebate too.
