  • Coffee grounds o.k for compost?

    Our council provides us with cornstarch bags, we put all our food scraps in there, we put it in our bio-wheelie bin, and its then composted. Do you guys reckon thered be any problem with putting coffee grounds in there? Its probably o.k just wondering if its too acidic/potent or something??? Smells pretty potent :-/

    Hi, i have no science to back it up but believe it would be fine. Some people spread it on their own gardens and after all it is a food product.

        GJs and *$s if I remember have bags of used grounds that you can take away specifically for your garden

        ive emptied out the knock box straight onto the garden many times with no ill effects

          I also use the grounds in my compost. You can also put it around the veggie patch to deter snails/slugs (not sure if true or not, seemed to work for me)

            Been putting them in my compost for the past 20 years. Veggie patch doesnt seem to mind at all.

              Theres lots of talk that coffee beans contain lots of nitrogen, which is good for making plants grow.

              I havent found any real studies on roasted, extracted grinds - its all heresay as far as I can tell.

              I do chuck it out on the lawn & garden and I havent noticed any dead patches yet!

                Not hearsay (or heresy ). Not sure how you judge what qualifies as a real study but see this study

                  Ive found (as have other) that the Black Soldier Fly larvae particularly love used ground coffee. They are a harmless fly (no mouthparts in adult stage I believe) that accelerates the early stages of composting.

                    Personally, I dump my bangbox into my vermiculture unit, Yep, Worms just LOoooooooove coffee as much as I do, they certainly are thriving with it

                    So yeah, Although Caffeine is an insecticide, it doesnt seem to affect worms all that badly when used grounds are dumped into the pot

                      Wow, thanks for all your great responses. Great to hear coffee grounds in the compost or garden are actually a good thing. Next time I have a veggie patch Ill definitely try it as a natural pest deterant!

                        This may be slightly off-topic, but we have 2 large dogs who occasionally feel inclined to dig big holes in the yard when we are at work. Ive experimented with different materials to put into the holes (looking for a doggy-deterrent of course). Ive found that coffee grounds work really well - the dogs wont dig in the same place after Ive empied the knock box into the hole, then filled over it with soil. (a bit of dog poo works best, but sometimes the holes are dug a bit too close to the house, so thats where the coffee grounds come in handy).

                        I do realise that this is probably too much information for most people!!  :P

                          Some here might say that the supermarket brands are ideal for the compost, even before being used

                            we had a serious "snails eating the mails" problem in our letterbox. a nice layer of coffee grounds in the bottom of the letter box sorted that right out

                            all of the rest of the grounds go to the compost and then on to the worm farm and we have no issues...

                              I never knew coffee grounds could be so useful!
