Can I do anything to strengthen my rubber tree plant trunk?

my rubber tree plant is growing like a weed all of a sudden but the trunk seems to to be to weak to support it it upright. I have staked and tied it up is there anything else I can do?

Hi,

Choose one of the new branches that is naturally growing more toward the vertical and train it to grow upward (wire or stake it). Once it starts growing well, prune off what is growing above the new leader.

This shortening reduces the weight on the stem and has the same effect as strengthening it. Also, the stem continues to increase in diameter as the new leader grows, strengthening it and adding interesting taper to the trunk.

Good thing prkswllflwr answered you I was going to suggest rubber cement. . . .
