Coffee Grounds

  1. 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.
     
  2. Best used in compost, pretty acidic if just made or whatever
     
  3. 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.

    compost that shit :D it is high in nitrogen, if that is the nutrient you are looking for.
     
  5. 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.
     
  6. Edit-

    I use Folgers and it works fine. I am sure the organic beans just adds to the beneficial fertilizer. :smoking:
     
  7. 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.
