Can these grow in containers or must be planted?

There's no way the bit of dirt, compost and 3 bags of dirt will be enough for the 4 bins. Will have to see if I can mix a bit of clay as well. Maybe then it'll be okay.
Too busy today, so working on it tomorrow.

Used everything laying around. Still not enough. Really don't want to add the clay.

Still not enough....But got them in anyway.
