Calculate grass seed, sod, plugs, fertilizer, watering and service cost for a Texas lawn. This page is designed for Bermuda, St. Augustine, Zoysia, Buffalograss and Tall Fescue lawns across Dallas-Fort Worth, Houston, Austin, San Antonio, West Texas and South Texas.
Texas lawn care is different from a generic national schedule because the state covers humid Gulf Coast turf, drought-prone West Texas yards, North Texas freeze risk and South Texas near-tropical growth.
The calculator starts with lawn size, then adjusts by grass type and region. It separates grasses that can be seeded, like common Bermuda, buffalograss and Tall Fescue, from grasses that are normally installed by sod or plugs, such as St. Augustine and many Zoysia lawns. This is important because a St. Augustine seed estimate would be misleading: homeowners need sod square footage or plug counts, not pounds of seed.
Texas A&M turf guidance consistently points to adaptation first. A turfgrass must fit both the broad regional climate and the microclimate of the yard: sun, shade, soil, drainage, irrigation and traffic. A full-sun DFW front lawn can be managed very differently from a shaded Houston backyard or a low-water West Texas property.
The calculator also gives a water target in inches and gallons. One inch of water over 1,000 square feet equals about 623 gallons, so even small changes in watering frequency can change the monthly water bill. Use the output as a planning estimate, then measure your own sprinkler output with catch cups and follow local city watering rules during drought stages.
For full sun and heavy use, start with Bermuda. For shade and Gulf Coast humidity, consider St. Augustine. For a dense premium lawn, compare Zoysia. For low-water western landscapes, evaluate Buffalograss. For North Texas shade only, Tall Fescue can be an option but it needs summer care.
In Texas, lawn success is usually limited by water management, not only fertilizer. Overwatering St. Augustine can push disease, underwatering new sod can kill it quickly, and watering restrictions may force a lower-input strategy. Cost also matters because sod, irrigation repair and professional mowing prices can exceed the original grass seed budget. The best lawn plan is the one you can maintain through July and August, not just one that looks good in April.
| Region | Best choices | Main caution |
|---|---|---|
| Dallas-Fort Worth / North TX | Bermuda, Zoysia, Tall Fescue in shade | Winter freeze + summer heat |
| Austin / San Antonio | Bermuda, Zoysia, St. Augustine in shade | Water restrictions and limestone soils |
| Houston / Gulf Coast | St. Augustine, Bermuda, Zoysia | Humidity, disease, chinch bugs |
| West Texas / Panhandle | Buffalograss, Bermuda, drought-tolerant blends | Low rainfall and wind |
| South Texas / RGV | Bermuda, St. Augustine, Zoysia | Long growing season and pests |
| Grass | Mow | Water | Establish |
|---|---|---|---|
| Bermuda | 1–2 in | ~1 in/week | Seed, sod, sprigs |
| St. Augustine | 3–4 in | 1–1.5 in/week | Sod/plugs only |
| Zoysia | 1–2.5 in | 0.75–1 in/week | Sod/plugs, some seed |
| Buffalograss | 3–4 in | 0.5–0.75 in/week | Seed/sod |
| Tall Fescue | 3–4 in | 1–1.5 in/week | Seed/sod |
Use this calendar as a starting point, then adjust for your local soil temperature, rainfall, drought restrictions and the grass type you selected.
The best grass is not the one that looks best in a photo. It is the one that fits your light, water, traffic and maintenance level.
Best for full sun, kids, dogs and heavy traffic. It recovers quickly, tolerates heat and can be seeded. It struggles in shade and may invade beds if not edged.
Best for shade and humid regions. It is broad-bladed, lush and common in Houston and South Texas. It needs sod/plugs, higher mowing and careful chinch bug monitoring.
Best for a premium dense lawn with slower vertical growth. It is more shade-tolerant than Bermuda but slower to establish and often more expensive up front.
Best for low-water, full-sun, natural landscapes, especially West Texas. It is not ideal for heavy shade, high traffic or homeowners who want a lush dark-green carpet all year.
Dallas-Fort Worth sits in a transition area where both heat and occasional hard freezes matter. Bermuda is the safest full-sun choice. Zoysia can work well for premium lawns, while St. Augustine is usually reserved for partial shade and should be planted with cold risk in mind. Tall Fescue can work in shaded areas but needs more summer irrigation and is not the default full-sun lawn.
Austin and San Antonio lawns often face water restrictions, rocky soils and hot summers. Bermuda performs well in sun. Zoysia can provide a dense turf with less vertical mowing. St. Augustine is useful in shade but must be watched for pests and irrigation stress. Buffalo grass and native blends are increasingly practical for homeowners prioritizing lower water use.
Houston and nearby regions support St. Augustine very well, but humidity increases disease pressure. Bermuda is strong in full sun, while Zoysia can be a premium option where drainage is good. Avoid excess nitrogen and nighttime irrigation because leaf wetness and humidity can increase disease pressure.
| Site condition | Best choice |
|---|---|
| 6+ hours direct sun, high traffic | Bermuda |
| 4–6 hours sun, humid/coastal | St. Augustine or Zoysia |
| Low-water full sun | Buffalograss or Bermuda |
| Premium dense appearance | Zoysia |
| North TX shade | Tall Fescue or St. Augustine |
| Dog traffic | Bermuda first, Zoysia second |
Bermuda will thin in shade, St. Augustine can fail in severe cold, Tall Fescue struggles in Texas heat, and Buffalograss will not look like a lush irrigated St. Augustine lawn. Match the species to the site before spending money.
Good Texas lawn care is mostly about avoiding extremes: too much water, too much nitrogen, mowing too low, or starting projects during restrictions.
Use deep and infrequent watering as the default. For an established lawn, this means watering enough to wet the root zone, then allowing the surface to dry before the next irrigation. Frequent shallow watering keeps roots near the surface and makes the lawn less drought-resilient. New sod and seed are different: they need frequent light water until rooted or germinated.
Fertilizer should follow active growth. Bermuda, St. Augustine and Zoysia should not be pushed with nitrogen while dormant. Wait for green-up and at least one or two mowings. Soil testing helps determine whether phosphorus or potassium is actually needed. In many cases, a nitrogen-focused lawn fertilizer is enough, but potassium may matter where drought, wear or winter stress is a concern.
Mowing height protects the plant. Bermuda can be kept lower, St. Augustine should be higher, and summer stress usually calls for the upper end of the recommended range. The one-third rule remains the safest standard: do not remove more than one-third of the leaf blade in one mowing.
Measure sprinkler output, repair broken heads, avoid runoff, follow city rules, water early morning and reduce nitrogen during drought stress.
Feed only active turf, avoid late-season nitrogen on warm-season grass, use soil tests, and do not fertilize before heavy rain.
Sharpen blades, mow frequently enough for the one-third rule, raise height during heat, and avoid scalping St. Augustine.
Scout before treating. Chinch bugs often hit hot St. Augustine edges, while grubs and armyworms require correct identification and timing.
| Grass | Typical active-season plan |
|---|---|
| Bermuda | Higher N during active growth if irrigated and mowed often |
| St. Augustine | Moderate N; avoid pushing disease-prone growth |
| Zoysia | Moderate to low N; avoid excess thatch |
| Buffalograss | Low N; keep program minimal |
| Tall Fescue | Fall feeding; light spring only |
| Area | 1 inch water | 0.5 inch water |
|---|---|---|
| 1,000 sq ft | 623 gal | 312 gal |
| 5,000 sq ft | 3,115 gal | 1,558 gal |
| 10,000 sq ft | 6,230 gal | 3,115 gal |
| ¼ acre | 6,784 gal | 3,392 gal |
Use these as starting assumptions for local pages, service-area content, and city-specific calculator notes.
Bermuda is the default full-sun lawn. Zoysia is a strong premium option. St. Augustine needs protected sites and cold-tolerant varieties. Clay soil makes aeration and irrigation distribution important.
St. Augustine dominates many neighborhoods, especially shaded yards. Watch chinch bugs, gray leaf spot and irrigation runoff. Bermuda thrives in full sun but loses in shade.
Bermuda, Zoysia and St. Augustine all work depending on sun. Use soil testing and watch watering ordinances. Low-water designs may favor Bermuda, Zoysia or native options.
Bermuda is reliable in sun; St. Augustine works in shade with irrigation. Raise mowing height during summer and avoid unnecessary nitrogen in peak heat.
Buffalograss and drought-tolerant Bermuda are usually more practical than thirsty shade grasses. Irrigation capacity and wind exposure should guide every grass choice.
Warm-season lawns can stay active much longer. Pest pressure and irrigation timing matter. Pre-emergent and fertilizer windows arrive earlier than North Texas.
These examples show how the calculator output can be interpreted before buying materials or requesting a quote.
Most failed Texas lawn projects come from timing, species mismatch or water management problems, not from a lack of products.
Warm-season turf should be fed when it is actively growing, not when it is still brown from winter dormancy. Early nitrogen can feed weeds, encourage disease-prone growth and waste money. Wait until the lawn is mostly green and has needed mowing.
St. Augustine is established from sod, plugs or sprigs. A real St. Augustine lawn is not grown from seed. If a shaded Texas yard needs St. Augustine, budget for sod or plugs and protect the area from traffic during establishment.
Brown patches can come from dry sprinkler zones, chinch bugs, fungal disease, compacted soil, dull mower blades or dog urine. Check soil moisture and pest signs before adding irrigation time. Overwatering can make several problems worse, especially in humid Gulf Coast lawns.
| Symptom | Likely checks |
|---|---|
| Brown sunny patches in St. Augustine | Chinch bugs, dry edges, heat stress |
| Thin Bermuda under trees | Shade, not fertilizer deficiency |
| Runoff after short watering | Compaction, slope, sprinkler rate too high |
| Yellow but wet lawn | Overwatering, iron deficiency, disease |
| Weeds after spring | Pre-emergent was late or missed |
