The answer to 'difference between sod' is that sod and seed are two main options for establishing a new lawn. Sod is pre-grown grass that is harvested, transported, and installed in rolls or pieces. Seed is individual grass seeds that are spread and grow into a new lawn over time.
The key differences are that sod provides an instant, mature lawn while seeding takes several weeks to germinate and grow. Sod is more expensive upfront but establishes faster, while seeding is a more affordable option but requires more time and effort to establish. Both have their own benefits and use cases depending on your timeline, budget, and lawn requirements.
