I have this plant for 20yrs. Now I may have to leave it on my terrace until the end of Christmas. How is the best way to treat it so it doesn't die. Would appreciate your advise and should I cover it due to winter weather. Thank you

Unfortunately, these are very sensitive to cold weather, and may start to suffer below 60 degrees. In fact they are sensitive to any drastic change in temperature. It is best to bring this plant inside if you think it will get below this where it sits now.
