How to Lay Sod: Step-by-Step Process

If the ground is prepped right, sod can be installed at any time of the year. However, it is always better to avoid sodding during heavy rainfall or snowfall. If the weather is hot and dry, you should avoid sodding. The best times to sod are during spring and early autumn. This is because the temperature is cool and the rainfall is in the right amount which helps the sod grow roots faster. The best time to lay sod also depends on the kind of grass you are growing. For instance, if you are planning to grow grasses like centipede and zoysia, you should consider slightly warmer temperatures of later spring.

A healthy base layer of topsoil is essential. Aim for 3 to 4 inches of nutrient-rich, well-draining topsoil across the lawn area. Level the surface so it sits about 1 inch below driveways, sidewalks, and edging. Before laying sod, lightly compact the soil with a roller and ensure it’s moist (but not wet) to promote root contact and reduce air gaps. Adding compost or starter fertilizer can further boost root establishment.

Yes — the soil should be moist but not muddy before installation. Lightly water the area the day before or the morning of sod delivery to ensure the top 1–2 inches of soil are damp. This helps sod roots bond quickly with the ground, while preventing muddy conditions that can interfere with alignment or cause rutting during installation.

No. Installing sod over existing grass prevents root contact with the soil and leads to poor establishment, uneven growth, and decay. Always remove old turf, weeds, and debris, then loosen and level the topsoil before laying new sod. While decaying grass might provide some nutrients, it’s more likely to create drainage and root issues if left underneath.

Sod begins to develop shallow roots within 7–14 days if watered properly. Deeper root establishment typically occurs between 3–6 weeks, depending on temperature, watering consistency, and soil prep. During this time, reduce watering frequency gradually to encourage deeper rooting. Avoid mowing or heavy foot traffic until sod resists a gentle tug.

Avoid walking on new sod for at least 2–3 weeks. Foot traffic during this stage can shift sod pieces, damage delicate roots, and cause uneven settling. Wait until the sod is well-rooted and passes the “tug test” before allowing pets, kids, or mowers on the lawn. Hold off on digging or installing heavy objects for up to a month post-installation.

Wait until the grass reaches 3.5 to 4 inches in height, typically around 2–3 weeks after installation. Ensure roots are well-established before mowing to avoid pulling up sod. Use a sharp mower blade, and follow the ⅓ rule: never cut more than one-third of the grass blade height at a time to reduce stress.

Yes. Overwatering is a common mistake that can lead to root rot, fungal growth, or shallow rooting. Newly installed sod should be watered daily for the first 7–10 days, then gradually reduced. Soil should remain consistently moist, but not soggy. Use a soil moisture meter or test with your finger to avoid drowning the roots.

Yes. Dog urine contains high levels of nitrogen and salts that can burn sod and create yellow patches, especially while it’s still rooting. While a small amount of nitrogen can be beneficial, repeated exposure in the same area overwhelms the sod. Training your dog to use a designated area or rinsing the spot with water immediately after urination can help reduce damage.

Dogs should stay off newly sodded lawns for at least 14–21 days, but ideally up to 6 weeks, to allow for full root establishment. Early access can result in turf shifting, urine burns, and compaction. Until the lawn passes the tug test and watering has been reduced, treat your sod as a fragile surface.

Sod offers instant results, faster usability, and fewer weeds, while seed is more affordable and easier to transport but takes longer to establish. Choose sod if you need a quick fix, erosion control, or uniform appearance. Choose seed if you have time, a limited budget, or want to customize your lawn’s grass type.

Possibly. Yellowing sod is often caused by heat stress, improper watering, or poor soil contact. If the sod is still alive, you can often revive it with consistent watering, improved soil aeration, and a light application of starter fertilizer. Check for drainage issues and avoid overwatering. In some cases, yellow patches may need to be replaced.
