I've been reading about herbs in containers, and I'm wondering how big is big? I have rosemary, mint, dill, and parsley that I'd like to pot up. For the mint, I bought a 12" shallow clay pot. For the rosemary, it's in a 3" plastic pot right now, and I don't know how big the pot should be. I've heard everything from 8" to 11", but it's so little right now, it seems like it might drown in such a big pot. Any thoughts?
As for the dill and parsley, I have no idea how big the pots should be. Does it even matter?
