I might keep collecting them for a week and then have a break. I don’t want to unintentionally harm the plants. It’s a shame because this cafe is so happy to have me take the coffee grounds away!
The more websites I’m reading the more I’m finding studies stating coffee grounds inhibit plant growth.

I throw it loosely over my new garden beds which are mulched with pine needles. I felt great about it, but then read that contrary to peoples’ anecdotal evidence, coffee grounds are bad for soil. It’s alleopathic and some people say plants grow worse when it’s sprinkled around them. Yet on other sites people say coffee’s amazing for the soil and plants.
What do you think? Unfortunately I can’t just compost it as I don’t have room. Sprinkling it over pine needle and other leaf mulch is the only feasible way for me.

I threw 50 lbs of ucg's on an urban lot the other day and couldn't even tell. I could have used another 200 lbs to even start to make a difference.
Most of my research states that coffee is acidic and coffee grounds are neutral and Red Worms do quite well with coffee grounds.
Currently I use ucg frequently and then make "instant" coffee to rinse the buckets out and fling that as well.
My neighbors enjoy watching me.
