if you want a
green lawn year round
you have to increase the organic matter in the soil
namely
HUMUS
Humus is created by soil bacteria (takes forever)
and more effectively by earthworms as
what comes out of the south end (castings)
is PH perfect and will hold ten Times it's weight in WATER
and that is the "
key"
that being said... know this, a typical acre of land
which is aproximately 200 by 207 feet... can hold up to
1,000,000 earth worms but generally that acre on average
only has populations of around 10,000
so a 50 foot square can have as many as 250,000 but generally
has very small numbers
keeping the grass longer at the 4 inch mark allows for more shade
cast and keeps the soil medium cooler and a better habitat for worms
all these weed products and chemical fertilizers basically kill them all.
feed the worms and they'll feed the lawn if you want one that is
in the fall you don't rake up all your precious maple leaves
and haul them away.... think of them as dollar bills
rake them into windrows like they do hay before baling it
then run it over with your mower until it's turned into confetti
you can buy Purina worm chow for 20 bucks for a 50lb bag
and broadcast spread it on (or prior to)
one of those drizzle nights to feed them
