Installed sod is LawnStarter's range by grass type on a prepared site; grading, soil and delivery ($65–$230) can be extra. Seeding ranges are professional prices with seed included.
Sod buys time; seed saves money. On a 2,000 sq ft lawn the gap is more than ten to one: LawnStarter's October 2026 cost guides put a professionally installed sod lawn that size at about $3,300, while professional seeding runs $0.09–$0.15 per square foot. Which one is right depends on the season, the slope, the grass the client wants and how soon they need it to look finished. If you already know it will be sod, the sod calculator counts the pallets; if it will be seed, the grass seed calculator gives you pounds by grass type.
Sod vs. Seed, Side by Side
| Factor | Sod | Seed |
|---|---|---|
| Cost (2,000 sq ft, pro) | About $3,300 installed (LawnStarter average) | $180–$300 at $0.09–$0.15 per sq ft |
| Time to a green lawn | The day it goes down | Germination in about 1–3 weeks, then a season to fill in |
| Best planting window | Most of the growing season, with enough water | Fall for cool-season grass; warm-season seed needs the warm months |
| Grass choices | What local farms grow | Any seeded variety, blends for sun and shade |
| Warm-season grasses | Standard for bermuda, zoysia, St. Augustine | Bermuda and some zoysia only; St. Augustine is not seeded |
| Erosion and slopes | Holds soil right away | Washes out in heavy rain until rooted |
| Weed pressure | Dense from day one | Weeds compete with seedlings in the first months |
| Labor | Heavy: pallets, cutting, rolling | Light: spread, rake, keep moist |
What Each Costs in 2026
Sod: LawnStarter's sod guide (updated October 5, 2026) averages $0.60 per square foot for the sod alone and $1.65 installed, with labor at $0.55–$1.00 per square foot and delivery at $65–$230. For a 2,000 sq ft yard that is about $1,200 for sod alone or $3,300 installed.
Seed: its seeding guide (updated October 9, 2026) puts professional seeding at $0.09–$0.15 per square foot and hydroseeding at $0.07–$0.21. Seed itself runs $2–$6 per pound for tall fescue and $7–$15 for Kentucky bluegrass. Seed's hidden cost is water and follow-up: a bare seedbed has to stay moist for weeks, and thin spots may need a second pass.
Either way the soil work is the same and is often the biggest part of the bill; the sod installation guide breaks it down step by step.
How Long Each Takes
Sod is a lawn the afternoon it is laid; it needs steady water until the roots knit into the soil below. Seed is slower. NC State's turf team says cool-season seed usually germinates in 5 to 10 days at the right temperatures, and Iowa State Extension tells homeowners to expect germination within 2 to 3 weeks. Both agree the seedbed has to stay moist the whole time, which in practice means light watering at least once a day.
Timing matters more for seed than sod. NC State calls fall the best time to seed cool-season lawns (mid-September to early October in the Piedmont), when the soil is still warm and weed pressure is falling. Iowa State puts its window at mid-August to mid-September. The overseeding timing guide covers the windows by region, and how to plant grass seed walks through the seedbed.

Your Grass Type Often Decides for You
University of Delaware Extension puts it plainly: all cool-season grasses (tall fescue, Kentucky bluegrass, perennial ryegrass, the fine fescues) are established by seed or sod, so in the North you genuinely have a choice. Zoysiagrass and bermudagrass are typically established by sod or sprigs, with only a few seeded varieties. In the South the question is often settled before the price is: Texas A&M AgriLife Extension notes that St. Augustinegrass is planted as sod, sprigs or plugs because seed is not available. The cool-season vs warm-season grass guide explains which group you are in.
Choose sod when
- The client wants a finished lawn now (a sale, an event, a new build)
- The area is sloped or erodes
- The grass is St. Augustine or another sod-only type
- It is late spring and seeding a cool-season lawn would fight summer heat
Choose seed when
- Budget matters more than speed
- It is early fall and the lawn is cool-season
- You are thickening an existing lawn, not starting from bare soil
- The site is shady and needs a shade blend no local farm sells as sod
Common Questions
Is sod worth the extra money?
When the lawn has to look finished now, sits on a slope, or is a grass that can't be seeded, yes. For a cool-season lawn with time to establish in fall, seed gets you to the same place for a fraction of the cost.
Is hydroseeding a middle option?
On price it sits with seeding, at $0.07 to $0.21 per square foot in LawnStarter's October 2026 guide. The mulch in the slurry holds moisture and seed in place, which helps on gentle slopes, but it still needs the watering and the time a seeded lawn does.
Can I lay sod in summer?
You can if you can water it every day until it roots. Heat makes the first weeks harder for sod and much harder for seed, which is why cool-season seeding waits for fall.
