Rattlesnake fern: yellow leaves, causes and fixes

Check these first

Likely causes

Underwatering
Most likely
How to tell: The leaves feel crispy or dry to the touch and the soil has pulled away from the sides of the pot. The plant may look generally limp.
What to do: Water the plant thoroughly until water runs out of the drainage holes. Maintain a schedule of watering every 3 to 7 days to keep the soil evenly moist.
Low humidity
Possible
How to tell: The edges of the leaves turn yellow or brown and feel brittle. This often happens in homes with dry heating or air conditioning.
What to do: Place the fern on a pebble tray filled with water or use a humidifier nearby. Misting the leaves occasionally can also help keep the air around the plant moist.

When to worry
