Likely causes
Insufficient Light
Most likelyHow to tell: The stems are very long and thin with large gaps between the leaves. The plant looks sparse rather than bushy.
What to do: Move the plant to a brighter location with more direct or bright indirect light. If indoors, consider a grow light for 8 to 10 hours a day.
Crowding
PossibleHow to tell: The plant is in a small pot and the stems are competing for space. It looks tangled and thin.
What to do: Trim back the longest stems to encourage bushier growth. Repot the plant into a wider container to give the roots more room to spread.

When to worry
Leggy growth is rarely fatal but it makes the plant look untidy. It is normal for the plant to stretch slightly if the seasons change and light levels drop.
Stopping it coming back
Provide consistent bright light throughout the year. Prune the plant regularly to maintain a dense, attractive shape.

Questions people ask
- Can I trim the long stems?
- Absolutely, trimming will encourage the plant to grow back thicker. Use clean scissors to cut the stems back to the desired length.
- Will more light make the leaves turn green again?
- Yes, better light helps the plant produce more chlorophyll and keeps the foliage vibrant. It will also help the stems stay strong and upright.
