    Hydrangeas like coffee grounds.

    they’re good around just about any plant, in moderation… they are favorites of worms, and the worms are good for the soil…. the tiny bit of acidity they contain isn’t going to change anything…. don’t allow them to clump on top of the soil or they will mold…. mix in or spread thin…..
