Hydroseeding could be described
as 1-step lawn planting.
Hydroseeding machines vary from large trucks to small
trailers, but they all have a water tank with an agitator, and are capable of
mixing grass seed, fertilizer, and paper mulch with water.
The mixture
is sprayed onto a new lawn area or slope that's been finish graded. The paper
fiber mulch usually has a green coloration to help the applicator visually tell where he's already sprayed. Highway slopes in
Pennsylvania are commonly hydroseeded with crown vetch due to its
aggressiveness and low maintenance characteristics.
Larger truck mounted hydroseeding units have a catwalk on top where an
applicator can shoot a water cannon while an assistant drives and
repositions the truck as needed. Smaller trailer drawn hydroseed
machines have
a long hose used by an applicator to 'spray paint' new lawns.
