Rubber Tree: Sick/Dying?
I have a 6' tall, 6 year old rubber tree. It was healthy its whole life, with the exception of always only having leaves at the top of each stalk. Recently, stalks/branches have been dying. (There are 5 thick "trunks" and 3 smaller ones.) The tips of the stalks lose all their leaves and shrivel. I have not moved the tree in 2 years, and water it sparingly, trying to keep the top of the soil moist. It is in a 1 ft deep pot with 18" diameter. I will admit to having never fertilized it until it appeared to be getting sick- then I gave it a little miracle gro tomato formula bc I was afraid all the N in the pot had been depleted. It doesn't seem to be improving, and this was about a month ago. New branches are dying off. Is there anything I can do to save it? What if I pruned a green branch, and tried to start a new plant from a smaller stalk of this larger plant? Will post picture asap.
