Check these first
- Observe how many hours of direct sun the plant receives daily.
- Check if the plant is leaning toward a window or light source.
- Inspect the stems for signs of new growth near the base.
Likely causes
Insufficient light
Most likelyHow to tell: The stems are thin and elongated with large spaces between leaf nodes. The plant may also lean heavily toward the nearest light source.
What to do: Move the plant to a spot that receives full sun or very bright indirect light. If you are growing it indoors, place it directly in a south or west facing window.
Lack of pruning
Most likelyHow to tell: The plant is tall and sparse but otherwise healthy. It has not been trimmed back in a long time.
What to do: Prune back the long stems by one third to encourage bushier growth. Do this in early spring to prepare the plant for the growing season.

When to worry
It is not a health emergency, but it will continue to look sparse until you provide more light or prune it. It is normal for the plant to grow tall over time if left unmanaged.
Stopping it coming back
Prune your Turk's cap annually in late winter and ensure it gets at least 6 hours of bright light daily.

Questions people ask
- Will my leggy stems fill back in?
- No, the existing bare sections of the stem will not grow new leaves. You must prune the stems back to encourage new, fuller growth from lower down.
- Can I grow Turk's cap in the shade?
- While it can survive in partial shade, it will become leggy and produce fewer flowers. Full sun is best for a compact and blooming plant.
