SOME INFORMATION ABOUT COFFEE GROUNDS:
HOW DO I USE COFFEE GROUNDS?
• Coffee grounds are about 2% nitrogen by volume.
• Grounds are not acidic; the acid in coffee is water-
soluble so the acid is mostly in the coffee.
• Coffee grounds are close to pH neutral
(between 6.5 - 6.8 pH).
• Coffee grounds improve soil tilth or structure.
• Coffee grounds are an excellent nitrogen source
for composting. They have a
C/N ratio of 20/1. In informal
trials with OSU/Lane County
Extension Service, Compost
Specialists sustained
temperatures of 140 O-160
OF have been recorded
for up to two weeks (when
coffee grounds were 25% of
the material in the compost
pile by volume).

• Spread the coffee grounds directly on the soil. Cultivate into the soil. If left to dry out they can
repel water in much the same way as peat moss that becomes dry.
• Spread on the soil and cover with leaves or compost or bark mulch.
• Incorporate directly into the soil, mixing in well, or lightly cultivating into the soil.
• Add to the compost pile by layering the ingredients using 1/3 leaves, 1/3 fresh grass
clippings and 1/3 coffee grounds.
• Add coffee grounds as part of a static compost pile, being sure to always add an equivalent
amount of a carbon source such as shredded paper or dry leaves. Mix together well.
• Coffee grounds are not a nitrogen fertilizer. In a germination test at the GrassRoots Garden
in Eugene, OR, coffee grounds were mixed with potting soil at a ratio of 25% by volume.
Lettuce seeds showed poor rates of germination and stunted growth compared to lettuce
seeds planted in potting mix without coffee grounds.
• If incorporating coffee grounds directly into the soil, add a nitrogen fertilizer at the same
time. Coffee grounds encourage the growth of microorganisms in the soil, which use
nitrogen for their growth and reproduction. While the grounds are being broken down by the
microorganisms the additional nitrogen in the fertilizer will provide a source of nutrients for
your plants.
• Paper coffee filters may be added to the compost pile as a carbon source. Shred or tear to
speed decomposition.
• Coffee grounds do not go bad. For future use store in 32- gallon trash container near
compost bin or pile.
