Can these grow in containers or must be planted?

23 of 30 survived.
Replanted the last ones. They'll winter over in these 4 big pots, then transplant further next year.

Read somewhere to use equal parts manure/compost, peat and grit for carrot soil.
So, here's my version and it fills the huge planter completely.
Hmm. I'll remove a couple of inches and then add the carrot seeds. Hope they grow long in here.



I also got 10 more of the huge planters. 17.49, plus 20% off. If they were 5 each, I would of gotten them all!
If the hostas do well in the others, I'll probably put each in it's own or 2 in each. Idk.
