I have a limitless supply from a cafe, but i’ve read coffee has some negative properties for plants, even when composted. Some sources say no more than 10% could be ok. I wonder how much other people use?
I’ll use compost only as potting mix and for raising seedlings, so I can’t risk anything negative to germination or fast seedling growth. I feel a bit worried I added coffee to my current compost bin.
Oh, for the problem of having TOO MANY coffee grounds! I can only dream.
I've got java envy.
