Likely causes
Insufficient light
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves.
What to do: Move the plant to a spot with more bright, indirect light. You can also prune the long stems back by half to encourage a bushier shape.
Lack of pruning
PossibleHow to tell: The plant is tall and sparse even though it gets decent light.
What to do: Pinch off the growing tips of the stems regularly. This forces the plant to send out side shoots.
