Sod is both grass and the soil directly beneath the grass held together by the roots. When used for individual lawns, it usually comes in 16×24 inch blocks. For larger sod projects, it may come in long strips which are rolled up like carpet.
Sod is sold to landscapers, home builders and home owners to form lawns, sports fields and parks. It’s placed on bare soil which the roots grow into over a period of time.
How is sod different from seeding?
Seeding involves planting the grass seeds in the spot that they will eventually grow. Sod, on the other hand, is already mature grass that takes root in a new location. Newly laid sod is ready for use in about thirty days. A seeded lawn takes much longer to grow and can’t be walked on until the grass is at least two inches tall.
