When you don't want your dracaena plant to grow any larger, repot the plant every third year to refresh to potting soil. Use the same size pot or one only slightly larger to confine the roots and slow growth. You can also control the height by simply cutting off the top of the plant. Two new stems will grow from the cut area within a few weeks.

When plants become too tall, cut off the cane at any height. New leaf clusters will grow from just below where the cane was cut.
