Using established turf (grass & roots) that is cut in thin layers and removed from the growing area in strips.

Sodding

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

Sprigging is slow if done by hand.

Sprigging & Stolonizing

Can be done by broadcasting plant parts and rolled or disked into the soil. Usually used on larger areas such as golf

courses.
