Why is my Lady fern looking thin and leggy? Causes and fixes

Check these first

Assess how much light the plant receives throughout the day.
Check the humidity levels in your home.
Look for signs of brown, crispy tips.

Likely causes

Insufficient Light
Possible
How to tell: The fronds will stretch out and become sparse as they reach for a light source. The plant will look weak and lose its lush, full shape.
What to do: Move the fern to a spot with bright, indirect light. Avoid direct sun, as this will scorch the delicate fronds.
Low Humidity
Possible
How to tell: The tips of the fronds may turn brown and crispy, causing the plant to look thin and unhealthy. This happens when the air is too dry for the fern to thrive.
What to do: Place the pot on a pebble tray filled with water to boost humidity. You can also mist the plant daily or use a humidifier nearby.
