Check these first
- Assess the light intensity in the current location.
- Check if the stems are leaning toward a window.
- Inspect the base of the plant for new growth.
Likely causes
Insufficient light
Most likelyHow to tell: The stems stretch out with large gaps between the needles as the plant searches for a light source. You might notice the plant leaning heavily toward the nearest window.
What to do: Move the pot to a spot with bright, indirect light. Avoid direct sun, which can burn the foliage, but ensure it gets plenty of ambient brightness throughout the day.
Lack of pruning
PossibleHow to tell: The plant looks healthy but has long, unruly stems that have lost their bushy shape over time. This is a natural growth habit for older, established ferns.
What to do: Trim back the longest, straggly stems to the base of the plant using clean, sharp scissors. This encourages the plant to put energy into new, bushier growth near the center.

When to worry
It is not a cause for alarm, as this is just the plant trying to adapt to its environment. You only need to worry if the stems become weak or yellow, which suggests a deeper health issue.
Stopping it coming back
Keep your fern in a bright spot and prune it lightly every few months to maintain a compact, bushy shape.

Questions people ask
- Will my leggy stems fill back in?
- No, the existing stems will not grow new needles in the bare spots. It is best to prune those stems back so the plant can grow fresh, lush foliage.
- Can I grow this plant in low light?
- While it can survive in lower light, it will likely become leggy and lose its fullness. Bright, indirect light is much better for keeping it compact.
