get some grass seed and experiment with it....
you can get grass seed to spout anywhere in three days....
the secret is to pre-germinate it...
thats what those big green spraying hydroseed companies do
and you can do it on a smaller scale...
you can soak it and then after the seed swells you can dry
out small batches on a window screen ....until it's just able to
distribute again ...
the vitamin b1 root stimulant
(1 or 2 drops per gallon increases root growth by 100 times normal
) then it's already growing....ready to take root.
thats real good for small area's....
large area's you have to use the traditional spreader....but " if " your
having to many crab grasses then grow your lawn
taller to shade
out the crab grasses
easily ....til they've lost the battle....
then you can start cutting it.... shorter and shorter.
