Likely causes
Fern Scale
Most likelyHow to tell: You see small, brown, or tan bumps on the undersides of the fronds that do not move. These pests suck the sap and cause the foliage to yellow and fall off.
What to do: Wipe the fronds gently with a damp cloth or a cotton swab dipped in rubbing alcohol. For heavy infestations, use an insecticidal soap spray once a week until they are gone.
Temperature Stress
PossibleHow to tell: The plant is near a cold draft or a hot radiator, causing the fronds to turn yellow and drop suddenly. This happens when the plant cannot adjust to the environment.
What to do: Move the plant to a spot with stable temperatures between 60 and 75 degrees Fahrenheit. Keep it away from windows that get cold in winter or heaters that blow dry air.

When to worry
If the plant is losing many fronds at once, it is a sign of a major problem. It is normal for the oldest, lowest fronds to turn brown and drop as the plant grows new ones.
Stopping it coming back
Check your plant for pests every time you water and keep it in a stable, draft free location.

Questions people ask
- Are these bumps on my fern leaves bugs?
- Yes, those are likely scale insects. They attach to the plant and feed on its fluids, which weakens the fronds.
- Will my fern grow back if it loses all its leaves?
- If the rhizome is still firm and healthy, it can grow new fronds. Keep the soil lightly moist and give it time to recover in a stable environment.
