Coffee grounds in potted flowers?

I heard coffee grounds are

Good on roses, but what if the rises are in pots? I also have petunias, marigolds, verbena, impatiens, zinnias, and a blackberry plant. They are all planet in miracle grow, and get a flower food added to their water once a month. Would coffee grounds be good on all of them? Is it only for flowers planted in the ground?

    It makes a good water holding mulch, but not too much.

    They're getting all the nutrients they need.

    Save the rest of the grounds for the compost heap.

    Coffee grounds in the soil make it more acidic. it is okay to put it in all of the plants you listed. No problem at all.
