Should I prune the leggy stems?

Yes, you can trim them at the base to help the plant look tidier. This encourages the plant to put energy into new, stronger fronds.

Will it grow back bushy?

With proper light and consistent moisture, the plant will produce new, fuller fronds. Patience is key as ferns grow at their own pace.

Rattlesnake fern: leggy growth, causes and fixes

Check these first

Move the plant closer to a window with indirect light.
Check if the soil has been drying out too much.
Trim back any dead or extremely weak stems to encourage new growth.

Likely causes

Insufficient light
Possible
How to tell: The stems will stretch out and look thin as the plant reaches for a light source. The fronds will also appear sparse and weak.
What to do: Move the plant to a spot with slightly brighter indirect light. Avoid direct sun, which will scorch the delicate fronds.
Inconsistent moisture
Possible
How to tell: If the plant dries out too much, it may drop older fronds and look thin. The remaining stems will look brittle.
What to do: Ensure you are watering every 3 to 7 days to keep the soil evenly moist. Do not let the soil dry out completely between waterings.

When to worry

Stopping it coming back

Provide consistent, bright indirect light and keep the soil moisture stable. Rotate the pot occasionally to ensure even growth on all sides.
