The answer to 'difference between sod and seed' is that sod is pre-grown grass that is cut into strips and installed, while seed is individual grass seeds that are spread and grown from scratch. Sod provides an instant green lawn, while seeding takes time to grow in but is generally more affordable.
Sod is best for homeowners who want an instant, mature lawn or need to establish grass quickly, such as for erosion control. Seeding is better for DIY projects or when you have a flexible timeline, as it's more budget-friendly. Sod typically costs $1-$2 per square foot installed, while grass seed is around $0.05-$0.25 per square foot.
