I found your website today and found it very helpful, but I still needed a bit more advice. I have had my rubber tree since 1991 when I found it in the last chance bin at K-Mart for 99 cents. I do well with half dead plants, if they come back I figure they are hard to kill! Well, it has now been planted in an old metal 10-gallon rolling mop bucket for the past 5 years. This allows me to move it easily and to put it inside for the winter and out side for the summer.
It is now hitting 6 foot tall measuring from the dirt to the top most leaf. I almost died when I read they can grow to 50'. Here are all the questions I have. I'm figuring I can't plant it outside where I live because it gets too cold in Pittsburgh PA, that and the fact I've never seen one growing outside here. Second, there are roots starting to poke straight out of the lower 8" of the bottom trunk. Again I'm assuming it needs planted in a bigger deeper pot? At this point I won't be able to move it, it will be too heavy. Any advice? Third, can you prune the top? I found your article on pruning helpful, but it didn't mention the tops of the main trunk.
Thank you so much in advance for anything you might be able to help me with. This is my favorite plant. I've had it the longest, it outlasted my ex-husband (lol), and it has been to every state I've lived in.
