Yes! You can compost coffee, and more importantly you should!
- Composting your organic Just Coffee Co-op coffee grounds (and filters) helps reduce organic waste in landfills
- Coffee grounds have about 2% of nitrogen by volume
- Coffee grounds are not acidic (after brewing, the actual coffee you drink contains the acidity)
- Coffee grounds are nearly neutral in pH (ranking in 6.5-6.8 pH)
- Coffee grounds improve soil tilth or structure
How To Use Coffee Grounds In Your Compost/Garden:
- Spread grounds directly on to soil and work in a bit. (If left to dry on top, it can repel water – no bueno for the plants)
- Spread on the soil and then cover with compost or yard mulch (leaves, clippings, bark)
- Work it in with soil, mixing it well before planting (if you do this, you will want to add a nitrogen fertilizer to balance)
- Add to your compost and mix well – be sure to always have a balance between grass clippings, leaves or brown litter, and coffee grounds
- Compost your filters – shred them for faster decomposition
Now sit back, sip your coffee, and watch your garden grow!
