Dracaena plants like to be root - bound and should never be re-potted until the roots fill the existing pot. Once the roots of your plant have filled the pot, move it to the next size container but nothing larger. Many times, if you don't water deeply and only sprinkle water on the surface, the roots do not develop properly and the plant is not anchored well in the container. This causes the plant to tip over even though it has not out grown the pot it is in.
