I’m not going to win any breaking-news awards for this, but coffee grounds make great compost additions. If you drink coffee, save the grounds. If you don’t drink coffee, I’m not sure how you are reading this because you probably aren’t human. You are probably a zombie. Or some other undead abomination. Please check yourself by asking:
- Do I like to eat brains? (If yes, you are probably a zombie.)
- Do I shamble instead of running even when pursuing the living? (If yes, you are probably a zombie.)
- Does the sunlight burn me? (If yes, you are probably a vampire.)
And speaking of things that decay, even your paper filters that you use with coffee can go right into the compost pile. Just don’t use the yucky bleachy kind.
A lot of the larger coffee shops do offer their grounds to complete strangers. Shamble in and ask.
Within Your Compost Pile
Add coffee grounds for a boost of nitrogen and heat to your compost pile. As with most things composty, don’t add too much. 20% of your ingredients as coffee grounds is pretty good. If you’ve got a bucket of coffee grounds that you save in your kitchen, it will probably mold (especially if you save the grounds hot and wet), but that’s okay. Add it to the compost anyway.
Within Your Vermicular Bin
Worms dig coffee. They are practically human in their love for it. They will thrive on the grounds added and the filters. Watch your pH because coffee adds acidity. Lime or eggshells will help balance that out.
As A Mulch
If you’ve got a crazy coffee habit or perhaps you own Starbucks or a villa in Columbia, you could mulch with the grounds. Acidity again can be a bit of a problem, but nothing that can’t be countered.
