I'm building a greenhouse to keep the squirrels out, and to grow some dwarf mango and citrus. The house will be irrigated with hydroponics (or aquaponics). My questions have to do with the trees. Would it be better to plant them in the ground, or could I keep them in pots? If I did put them in pots, how big would they need to be? And finally, what media would you recommend in the pots?
