Sure can, as long as the branches still flex it will be a pretty easy job. Keep all the sides of the trelis secure to the walls or a frame or whatever cuz when the plants grow they will try to take that thing up with em. You can even use adjustable zip ties or twistie ties to keep the branches where you want em . Used to to this years ago on smaller grows and after the branches were bent flowering sites that would have normally grown a small bowl were growing small grams!
