London, England

I have a tomato plant that has grown a few leaves, but for the past few weeks it has stopped growing and is only about 4 inches in hieght. The leaves look healthy and lush, but the plant is not growing.
It was a casualty to a bad break, where the whole root area broke off. I used some organic rooting powder when I replanted it in to try and grow new roots as I have heard that they can grow new roots.
Is there anything that can be done, or do I need to dig it up and start again?

It is in a plastic tub, if that is relevant.
