Lawn care depends on your location and type of grass. I've got the
best lawn in the neighborhood and my neighbor started paying me $200 a
month to "do whatever I do to my lawn to his lawn." After 5 months,
his lawn looks much better, but not quite there yet. I fertilize,
test pH, mow high and often, overseed, spot treat weeds, and use
crab-grass prevention applications. You have to know what to do, how
much and when.
