I'm not sure where to post this. I suspect it's been covered before, but I don't know which forum. Actually, I wish they had a forum titled "Potted Plants," since it is different than planting in the ground. Anyway, since this is an experiment to me, thought I'd try it here.

In outdoor plants in pots and planters (not in the ground), are coffee grounds good for them? How much is too much (percentage of coffee grounds to potting soil or dirt)? Thanks for any thoughts on this.

I still think a potted plant forum would be a good one to have :)
