Q.Soil Depth Indoor Rubber Plant

Anonymous added on May 14, 2011 | Answered

Do you have a guideline for the size and shape of pot that is good for an indoor rubber plant? Mine right now has grown to 30 inches high and spreads out to 27 inches wide. It is in a pot that is only 4 1/2 inches high and 9 3/4 inches wide. Do I need to repot it now and in what size and shape of pot?

Generally, you should go one or two pot sizes up. In addition, you could try root pruning. When the roots are filling the current container and you don't want a larger one, then root prune the plant to about 1/3 of the roots in summer. I would also top prune 1/3 of the foliage to prevent transplant leaf drop. Afterward, repot with fresh soil in the same container (or choose a larger one if desired) and water thoroughly. Do not water again until the soil becomes dry or new growth appears, at which point you should care for the plant as usual. Repeat the process as needed.
