Likely causes
Insufficient Light
Most likelyHow to tell: The stems are stretching out with large gaps between the leaves.
What to do: Move the plant to a brighter location with consistent, bright indirect light. Avoid direct sun, which can scorch the foliage.
Lack of Pruning
PossibleHow to tell: The plant is tall and sparse but otherwise healthy in color.
What to do: Gently trim back the longest stems to encourage fuller, bushier growth. Do this in the spring when the plant is actively growing.

When to worry
Legginess is rarely fatal but indicates the plant is unhappy with its environment. It is normal for the plant to grow slightly thinner during the darker winter months.
Stopping it coming back
Provide consistent bright, indirect light throughout the year. Rotate the pot occasionally so all sides receive equal light.

Questions people ask
- Will the leggy stems fill back in?
- Once a stem is leggy, it will not grow leaves in the bare spots. It is best to prune it back to encourage new, compact growth.
- Can I grow this in full shade?
- While it tolerates shade, it prefers bright, indirect light. Too much shade will almost always lead to a leggy, weak plant.
