Planting Trees in Outer Space

Say a group of people travel to a different planet where they have to wear spacesuits to live (because there's no oxygen and because of the atmosphere's density). What would happen if they planted trees from earth in a greenhouse on this new planet, completely sealed, with all the conditions necessary for the trees to live, but on that planet's soil instead of earth's soil? Would the plants still grow? Would they still breathe out oxygen like on earth? And, if not, is there any way to grow a lot of earth's trees in outer space? (because there's a limit to how much dirt they could bring on a spaceship)
