How to save a rubber tree plant that is losing leaves?

My daughter brought home a rubber tree plant from her place of employment. For many months it thrived. Since we tturned the AC it has started to lose leaves. We moved it but it is still losing leaves. The stocks look like they are drying up and it...

looks like it is dying. What can I do?

I used to grow rubber trees and I noticed that these trees can be rather fragile. I had some very impressive trees that after the stress of moving lost most of their leaves.

At this point your best bet is probably air layering the top and discarding most of the trunk.

What do you mean by air laying?

I have also been told you never move this tree. To move it is to cause it to lose leaves. I have had a rubber tree for 15 years.

I read about someone bringing a rubber tree back by changing it's soil and adding a b12 to it. They also like to be dusted and wiped clean with a damp cloth.

I will see if I can find the info on how that guy replanted his. But I know you are not suppose to plant them in a pot too big. They are suppose to be somewhat root bound.
