Those are lovely mixes of herbs with a bit of lettuce thrown in! Once it grows in it should be gorgeous. I hope you have it near the kitchen door, I know for mw, the closer to the kitchen the more I use my fresh herbs.
I'm betting it depends on how wet your planting area is. Here, you have to jump back once it touches the ground and hope it doesn't outrun you. Seriously! We planted some in a old cast iron bathtub that was left in our backyard at our first home in Portland. It filled the tub frighteningly fast. But even before that, it shot out runners in all directions and tried to escape to the main garden. The only plant that I've seen that is worse for spreading is Creeping Jenny.
As someone else said, I'd nip off the leaves from about half way down and maybe lay the pots on the side and once they reorient, either up-pot them or plant them outside if the weather permits.
Oh lord, please don't put that mint in the ground in your main garden. Once it goes nuts, you'd have to get every scrap out or it'll regrow.
I'm so sorry Sueby, that sounds miserable.
We've tried to mix varieties of mint the the same pot but the common mint always outgrows everything and fills the pot with roots. We uproot it, trim it back roots (it always looks like there is no soil at all) and all then replant it to let it go nuts again.
I've been tempted to plant it in wet ditches in the past. Actually did once and I figure whoever lives there now curses me.
Oh THIS! I have a 8 gallon pot of the stuff in front of the covered run and thanks to you, I'll put it into the open run today!
Oh man that stuff is so hard to dig out. If you try to pull it up like a normal weed, you end up with a handful of leaves and the root stays put. Try dynamite.
