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.
