How to lay sod down properly for a new lawn installation?

To lay sod properly for a new lawn installation, first prepare the soil by removing debris and tilling the area. Then, lay the sod in a staggered pattern, ensuring the edges are tightly butted together. Water the sod immediately after installation and keep it consistently moist for the first few weeks. Avoid walking on the sod until it has rooted into the soil, typically within 2-3 weeks.
