I just recently received a corn plant from my father, who picked it up at an atrium he was working at. They switch the plants out every so often and just throw them away. It has been potted in a large pot (about 20in), and after some research about how to care for this plant I'm not sure if I should plant it in a smaller pot. It is about 4 feet tall and it is looking very sad (browning tips). I just dont want to shock the plant any more, seeing as it has been transplanted twice already. I really like this plant and would like to see it do well. any help is appreciated. Thank You, Amber
