styrofoam garden flats

[TychoMonolyth]

in the spring I get styrofoam flats with 9 tomato or other vegetable plants in it. When I'm ready to plant, I pop the whole thing out in one piece, split up the 9 plants and stick them in the ground.

pots like this: https://goo.gl/nsSHPG

Can I do the same with Pot plants?

Thanks.

There's no reason why you can't, that I can think of.

the roots could grow into eachother and the plants will compete for light that close together.

you would be better off in disposable cups.
