Low Humidity

The humid conditions of their native rainforest environment are ideal for bird’s nest ferns. Dry air will stress them out. Yellow leaves that are crispy at the edges likely need a humidity boost.

Temperature Extremes

Like Goldilocks, bird’s nest ferns want their environment “just right” – neither too hot nor too cold. Temperatures below 60°F or rapid shifts from hot to cold can induce yellowing.

Insufficient Light

Too much shade and the leaves pale from lack of light. But too much direct sun will scorch the foliage yellow too. Give them bright indirect sunlight for optimal color.

Poor Drainage

Letting bird’s nest ferns sit in water leads to root rot. Make sure the pot has drainage holes and use well-aerated soil to prevent yellowing from excess moisture.

Pests

Spider mites, mealybugs, and other creepy-crawlies can suck the life out of your fern. Inspect regularly and treat any invaders.

Old Fronds

As lower fronds age, they naturally yellow and drop off. This is normal, but excessive yellowing of older leaves may indicate an issue.

By identifying the specific cause behind the yellowing, you can take targeted action to rehab your bird’s nest fern.
