Sodding
Using established turf (grass & roots) that is cut in thin layers and removed from the growing area in strips.
Sodding
Is taken to new lawn & rolled out and fitted together.
More expensive than other methods, but…. Provides instant lawn. Works on slopes where seeds will wash
away.
Plugging
Using small plugs or blocks of sod to plant in holes about 1 foot apart.
Very time consuming, but…. Is used for many
warm season grasses that are poor seed producers.
Sprigging & Stolonizing
Uses plant runners, cuttings, or stolons without soil attached to start new lawns.
Sprigging is slow if done by hand.
Sprigging & Stolonizing
