DIY Sod Installation: Correct Soil Prep, Layout, and Watering Steps

A homeowner plans to lay sod over old weedy grass with gopher holes. Their proposed steps: 1) Roundup, 2) water, 3) rototill, 4) roll, 5) lay sod crisscross, 6) roll, 7) water. They ask if the process is right and when to fertilize.

Corrected Sequence

1. Apply Roundup; wait a few days to check for misses.
2. Rototill dry soil (swap water and till). Incorporate amendments (lime, P per soil test).
3. Rake smooth; water deeply once to settle. Re-grade hills/valleys; rake again. Do not roll wet soil.
4. Water soil evening before or few hours before sod delivery.
5. Lay sod immediately: stagger seams brick-style, butt edges tightly, avoid small pieces on edges.
6. Roll empty roller before watering for soil-sod contact.
7. Water thoroughly. Keep soil under sod consistently damp (not soggy) 7–10 days (30 min/day). Gradually shift to every 2–3 days, then weekly deep.
8. Test rooting: lift corner after few days; if it lifts like carpet, press back and wait.

Fertilizer Timing

Most apply after rooting to avoid burning tender roots. Some pros fertilize at tilling; both work.

Critical Tips

• Never till or roll wet soil.
• Work in sections: roll, water, then move on.
• Store sod in shade; mist on hot days.
• Fill wide seams with soil/sand before rolling.
