Grass Clippings as Organic Compost
Your lawn grasses are high in nitrogen, and other important plant nutrients.
Your lawn mower has already chopped it up into small pieces, which aids in
a speedy decomposition. Grass clippings should never be sent to the trash,
where it only takes up space. There are two places where grass clippings
should go: Using a mulcher mower, they can go directly back to your lawn,
to help feed it. Or, they can be composted for later use in your vegetable,
herb and flower gardens.
Grass clippings from your lawn makes great organic compost. At least it can
be. In order to use lawn clippings as organic compost, it is important, and
should be obvious, that you do not put any chemical or other non-organic
fertilizers on your lawn. And, that's the problem, as the majority of homeowners
put chemical fertilizers, weed killer and insecticides on their lawn, to
create a lush, green carpet of weed free and insect free lawns.
If you do use chemicals on your lawn, you can still use grass clippings as
a non-organic compost. Even if you wait several weeks after putting chemicals
on your lawn, residual chemicals can still be in the grass clippings. Use
chemically treated grass clippings in your flower gardens, and not around
vegetables or herbs, that you and your family will eat.
Because grass is rich in nitrogen, it is a great "starter" to a compost pile,
helping the decomposition action to get started. Do not stack large amounts
of grass in a pile to decompose. A big pile comprised solely of grass clippings,
will quickly become matted and gooey, producing a strong ammonia odor. In
making compost from grass clippings, it needs be mixed with other "brown"
compostable materials. The proper mixture is 60-80% green material.

You can also use grass clippings as a mulch. Spread them out thinly on an
empty space in the garden. Let them dry out for a few days. Take the dried
clippings, and spread them around plants, an inch or two thick. Do not let
them touch the stems of plants.
