Rubber Tree Doesn’t Grow
We have had our two and a half foot tall rubber tree plant for 2 years and it hasn't grown taller or wider. It sheds leaves once or twice a year, grows little ones near the top of the dirt, but never actually grows in height or width. Don't understand why. The pot it is in is big enough for the plant to be 10 feet tall, so I know the pot is not too small.
The pot might be too big! Plants fill the available soil with roots before they turn their attention to growing leaves. Also, the soil might have too much moisture. I once had a rubber tree that had been 1' tall with small leaves for several years. When I started to test the soil all the way to the bottom of the pot, and not water it until the bottom soil was feeling only the slightest bit damp, it almost overnight began to grow.
