How Tall Can a Rubber Tree Grow Indoors?

A 7-foot rubber tree (Ficus elastica) has the owner wondering about maximum height. In tropical ground plantings, they reach 80+ feet. Indoors, pot size limits growth. A 30-foot specimen exists in a conservatory.

Size Control

To keep it smaller, maintain a tight pot, prune roots and top growth. To encourage height, repot into progressively larger containers. All ficus species have tree potential—manage size by pot restriction and pruning.
