The Short Answer: 2-3 Weeks, and Pass the Tug Test First
As a general rule, wait 2-3 weeks before the first mow. Before you mow, do the tug test: grab a corner of the sod and pull gently. If it lifts easily, the roots haven't taken hold yet and it's not ready. If it resists, the roots have anchored into your soil and it's safe to mow.
Why Mowing Too Early Causes Damage
Before roots have knitted into the soil beneath, a mower's wheels and the shear force of cutting can shift or tear individual pieces of sod, undoing weeks of establishment in a single pass. It's one of the most common — and most avoidable — new-sod mistakes.
Don't rush it: a lawn that "looks ready" isn't the same as a lawn that "passes the tug test." Always confirm with the tug test rather than going by the calendar or how the grass looks.
Tips for the First Mow
- Set the mower to its highest cutting height for the first several mows.
- Make sure the blade is sharp — a dull blade tears grass rather than cutting it cleanly, which stresses new sod and invites disease.
- Never remove more than about one-third of the blade height in a single mow.
- Avoid mowing when the grass is wet — wait for it to dry.
The Full Establishment Timeline
| Timeframe | What's Happening |
|---|---|
| 0-3 weeks | Rooting phase — avoid foot traffic and mowing entirely |
| 3-4 weeks | Sod is typically rooted and traffic-ready; first mow with the tug test confirming readiness |
| 6-8 weeks | Full cosmetic maturity — dense, uniform coverage. Shaded areas under trees may take a week or two longer than sunny areas |
Ongoing Mowing Heights by Grass Type
| Grass Type | Mowing Height |
|---|---|
| St. Augustine (Seville, CitraBlue, Palmetto, Cobalt, ProVista, Classic) | Roughly 3.5-4 inches |
| Zoysia (Lobo, CitraZoysia) | Roughly 2-2.5 inches |
| Bahia | Roughly 3-4 inches |
