Check these first
- Observe how many hours of light the plant receives.
- Rotate the pot to ensure all sides get equal light.
- Trim back the longest stems to encourage branching.
Likely causes
Insufficient Light
Most likelyHow to tell: The stems are long and thin with large gaps between the leaves. The plant leans heavily toward the nearest light source.
What to do: Move the plant to a spot with brighter, indirect light. If indoors, place it near a south or west facing window.
Lack of Pruning
PossibleHow to tell: The plant is tall and sparse but otherwise healthy and green. It has not been trimmed back in several months.
What to do: Prune back the stems by one third to encourage bushier growth. Do this in early summer to help the plant fill out before the season ends.

When to worry
Some stretching is normal as the plant matures or prepares to bloom. Worry if the stems become so weak they cannot support their own weight.
Stopping it coming back
Provide plenty of bright light and prune the stems regularly during the growing season. This keeps the plant compact and full.
