I don't live near the ocean so the rock around here from teeny tiny to boulder size shouldn't be salty.But are we talking about putting these little rocks in potting medium or as a dressing on top of the pot.
This started out as a question of amending soil.I know sometimes i get side tracked and i babble so people probably end up not knowing what i'm talking about,been working on asking straight up questions!!
Bev, did you see the other thread it is called getting succulents ready for outside after overwintering!pork & beans,ghosty. Or something like that.
