I have 2 rubber trees that are single trunks and they are growing really tall. How can I get them bushy? They are over 6 feet tall. I took a clipping from a friend's aunt. I can't ask her, as she has passed away. I asked Home Depot workers and they don't know either. They are easy to grow, as I have a black thumb. I love them, but I am afraid that I won't be able to fit them in my house soon. Sharon's was bushy. Please let me know what to do so I don't have to throw them away. I didn't know they could grow so big. Thank you for any information you can provide.
