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 that gets full, direct sun for at least 6 to 8 hours a day. If it is in a container, rotate it so all sides get equal light.
Lack of pruning
PossibleHow to tell: The plant is tall and sparse rather than full and rounded.
What to do: Pinch back the tips of the stems in early summer to encourage branching. This creates a fuller, more compact shape.
