Quick answer: San Antonio lawns are warm-season turf — St. Augustine for shade, Bermuda for full sun, Zoysia as a premium pick, plus native low-water options for xeriscape. SAWS ties watering to the Edwards Aquifer level, so the schedule changes with drought stage. Questions? (210) 864-8662.
San Antonio Grass Types & Watering Guide
South-Central Texas is warm-season turf country, and an San Antonio lawn lives or dies on two things: the right grass for your light, and watering on the SAWS schedule. Soil varies sharply — deep Blackland clay on the east side, shallow stony alkaline clay over limestone on the Edwards Plateau to the north and west.
Which Grass Is Right for Your San Antonio Lawn?
St. Augustine — the shade workhorse
The most common San Antonio lawn grass because it handles shade better than other warm-season options. It is lush but thirstier and prone to chinch bugs in summer heat and brown patch in cooler, wetter spells. Best for part-shade yards.
Bermuda — full sun and traffic
Thrives in full sun and recovers fast from wear, the choice for open sunny lots. It goes dormant and brown in winter and thins in shade, so keep it to sunny areas.
Zoysia — the premium lawn
A dense, fine-bladed lawn with good drought tolerance once established and moderate shade tolerance. Slower to establish and pricier, but the premium pick where looks lead.
Native and low-water options for xeriscape
On full-sun, water-wise yards — common over the aquifer recharge zone and in the Hill Country — native and adapted plantings with decomposed granite and drip cut water use sharply while staying attractive.
San Antonio Watering Rules
Authority: San Antonio Water System (SAWS). The durable, normal-year schedule:
- San Antonio follows year-round SAWS watering rules tied to the Edwards Aquifer level; the allowed days and hours tighten as drought stages rise.
- Find your assigned watering day by address using the SAWS ‘Water on Your Day’ tool.
- Hand-held hose, drip, and soaker watering are generally allowed any time.
Current status (as of June 2026):
- SAWS Stage 3 is in effect: landscape irrigation once per week on your address-assigned day, allowed only 5 to 10am and 9pm to midnight.
- Drip and bubbler systems are allowed Monday and Friday in the same hours.
- The active stage is set by the Edwards Aquifer 10-day average — verify the current stage at saws.org before setting a controller.
Drought stages change — confirm the current rule with San Antonio Water System (SAWS) before you set a controller.
San Antonio Lawn Care Calendar
- Spring (Mar–May): green-up, first mow, pre-emergent, soil test. Do not prune live oaks — Feb through Jun is peak oak-wilt season.
- Summer (Jun–Aug): mow high (especially St. Augustine), scout for chinch bugs, water deep on your assigned day only.
- Fall (Sep–Nov): watch for brown patch, ease off nitrogen, plant trees and beds in cooler soil.
- Winter (Dec–Feb): warm-season lawns go dormant and brown — normal, not dead. Good season for hardscape and xeriscape projects.
Frequently Asked Questions
What is the best grass for a San Antonio lawn?
It depends on sun and water. St. Augustine is best for shade, Bermuda for full sun and traffic, and Zoysia as a premium dense lawn; native low-water plantings suit xeriscape yards. San Antonio is warm-season turf country, so cool-season northern grasses are not used here.
How often can I water my lawn in San Antonio?
SAWS ties watering to the Edwards Aquifer level. Under the current Stage 3 rule, landscape irrigation is once per week on your assigned day, only 5 to 10am and 9pm to midnight. Hand watering is allowed any time. Always verify the current stage at saws.org.
Why is my San Antonio lawn brown in winter?
Warm-season grasses like St. Augustine, Bermuda, and Zoysia naturally go dormant and turn brown in winter. It is normal and the lawn greens back up in spring.
When should I prune my oak trees in San Antonio?
Avoid pruning live oaks from February through June, peak oak-wilt season in South-Central Texas. Prune in the coldest part of winter or mid-to-late summer, and paint any cuts on oaks.
