Likely causes
Insufficient light
Most likelyHow to tell: The stems are long and weak with large gaps between the leaves. The plant leans heavily toward the nearest light source.
What to do: Move the plant to a location that receives full sun for at least 6 to 8 hours a day. If indoors, place it in a south facing window.
Lack of pruning
PossibleHow to tell: The plant is tall but not bushy. It looks sparse and has not been trimmed back in a long time.
What to do: Pinch back the top stems regularly to encourage branching. This forces the plant to grow outward rather than just upward.
