It's the wrong strategy, I think. "A plant" is, if you pull it out of the soil, not viable, because it can only exist in a complex network of dependencies of bacteria, fungi, and (to a lesser extent) animals. I think that's something even agriculture just begins to really appreciate. So to make that plant not just grow, but flourish, someplace else, you'll need to include or recreate this environment as closely (or functionally equivalent) as possible.

It's the same for us; people often get sick after moving far away, because they aren't used to the local bacteria and fungi yet. So if we ever intend to, say, travel to Mars, we'd better come up with ideas how we can safely maintain a stable ecosystem on a space station that actively accounts for bacteria, fungi, and probably even plants.
