I have never used coffee grinds as a soil additive, although I know they are very beneficial to some plants and flowers. I will be growing all of my vegetables in grow bags and using coconut coir this season, which itself contains no fertilizer or additives, it is pH nuetral.
My daughter works at Starbucks and was telling me of the "grinds" for gardeners bag they keep at her store. They brew fresh coffee every 30 minutes all day long so it piles up quickly. She says any gardener that wants them can have them free, they bag them especially for you. She has offered to bring me all that I want, but I'm not sure if any vegetable favors the acidic soil?
I will be growing a wide variety of everything this season and would enjoy the free product if I had any use for it.....any suggestions? Thanks!
Vegetables in grow bags or pots and coffee grinds......
The grounds are not acidic, so don't worry about that.
I put them in my raised beds to attract earthworms. The worms love the grounds. I don't know that they would be needed or would help with containers and coir. Maybe someone here has used them in containers and can tell you.

Thanks Karen! I am making a new raised bed this year, so I can at least use the grounds in that.
The starbucks near me has been saving their grinds for me for a couple of years now. I sprinkle them everywhere; in our part of of Texas--its really hard to over acidify anything, the soil here is right at neutral. They've never done anything but improve conditions. I pick them up about twice a week--on my way home from the post office. Great stuff--get as much as you can!
