Check these first
- Observe if the plant is leaning toward a window.
- Check if the stems are thin and weak.
- Measure how many hours of direct sun the plant receives.
Likely causes
Insufficient light
Most likelyHow to tell: The stems are stretching out and leaning toward the nearest light source.
What to do: Move the plant to a location with full sun or at least 6 to 8 hours of bright light. Rotate the pot every week to ensure even growth.
Lack of pruning
PossibleHow to tell: The plant is tall and sparse but otherwise healthy.
What to do: Pinch back the growing tips in early spring to encourage bushier, denser growth. You can trim the stems back by 3 to 5 inches to promote branching.
When to worry
It is not a health emergency, but it will make the plant prone to flopping over.
Stopping it coming back
Ensure the plant gets plenty of direct sun and pinch the tips regularly during the growing season.

Questions people ask
- Can I fix leggy stems?
- You can prune them back to encourage new, compact growth from the base.
- Will more fertilizer help?
- No, fertilizer will only make the plant grow faster in its current leggy state. Focus on light instead.
