I was wondering if coffee grounds were any good as a fertilizer / growing medium. I know people, my mom included, use coffee grounds on flowers and other plants. I drink a LOT of coffee, and not old, processed Folgers crap. Fresh, home roasted, organic coffee. I've read that pH has a lot to do with the overall health and development of the plant, and I was also wondering if coffee grounds were too acidic.
I read on a vermicomposting forum that used coffee grounds are only slightly acidic and can be used directly on the soil. However, if you topdress too many it'll form like a water resistant crust.
Yes it is acidic, I add very little to my planters. I advize you make a huge pot of coffee and just run more water through it, like extra spent coffee grounds. Luckily where I am, I have virtually no parasites to worry about.
Edit- I use Folgers and it works fine. I am sure the organic beans just adds to the beneficial fertilizer.
Thanks for the info guys! I don't think reusing the coffee grounds is necessary. I use a moka pot, which pretty much saps the grounds of all their oils and acids. I'll try using them in small amounts and compost the rest.
