Question
How would I Winterize Dracena.Is it possible to place it in smaller pot and leave it in the greenhouse(greenhose is not heated due to electrical expencee) Thank You Tony

Answer
Tony
There are numerous types of Dracenas...I am assuming yours is a tropical indoor plant...

Outside in a greenhouse with no heat in Ontario most tropical plants, if not all, will die when it gets too cold...It would have to be in a room with some sunlight or a grow lamp and the temperature should not go below 55 degrees.
Good luck.
