We have a rubber tree in the lobby that sits in front of floor-to-ceiling windows. It is growing well and we want it to keep getting bigger, however, what we don't want is for the stalks to get very long and tall, and then droop over. Right now it is staked but eventually the stakes will not be long enough. Is there a best way to prune it so the stalks don't get thin and droop over? Thanks for your help!
