I'm in Minnesota - I've got a big ol' ceramic pot on the deck that had
a great batch of spearmint in it. It's all brown and done for the
season now.

Now that winter is setting in, what should I do with it?
Trim it down & leave it outside? Put the pot indoors?

I'd love to have the plants get even bigger next year if possible, and
if I recall correctly, it's a pretty aggresive plant. That was my
main reason for keeping it in it's own pot vs. putting in the ground.

thanks for any advice.
