Starbucks'
"Grounds for Gardeners" Program*
Starbucks
aspires to be known not only for the quality
of its coffee, but as a socially responsible
company, both in the communities where it has
retail locations and the countries where our
coffees are grown.
To
help minimize Starbucks environmental footprint,
the company is committed to reducing waste generated
in our stores. Starbucks partners have discovered
that many of its customers are also gardeners.
This discovery led to the Grounds for Your Garden
program.
Coffee
grounds, mixed with other materials, are an
excellent source of nutrition for soil. Giving
away used coffee grounds not only makes customers
happy, but it reduces garbage in the landfills
and contributes to a healthier environment.
Coffee
grounds can be applied along with other materials
as a side dressing for vegetables, roses and
other plants. Coffee grounds are high in nitrogen,
but are also acidic. Adding brown material such
as leaves and dried grass to the grounds will
help keep a balanced soil pH.
Coffee
grounds act as a green material with a carbon-nitrogen
(C-N) ratio of 20-1. They make an excellent
addition to compost. Combined with browns such
as leaves and straw, coffee grounds generate
heat and will speed up the compost process.
To counter the acidity of the grounds, consider
adding a teaspoon of lime or wood ash for every
5 pounds of coffee grounds.
Worms
fed with coffee grounds combined with other
materials will flourish.
