When I firsted transplanted the chives I put three plants into one pot because they looked so small. I wonder now if that was a mistake because they have really taken off. I seem to remember that chives don't mind being a little crowded though so it'll probably be all right. I can separate them at some future time if need be. Having a pot of these has been a pleasant thing since I snip some to put into dressings and potatoes and what have you. So nice!
