Likely causes
Overwatering
Most likelyHow to tell: The fronds turn yellow or mushy and the soil emits a sour, swampy odor. You might notice the plant stays heavy and wet for more than a week.
What to do: Remove the plant from its pot and trim away any black, slimy roots with clean scissors. Repot the fern into fresh, well draining potting mix and ensure the container has plenty of drainage holes.
Poor Drainage
Most likelyHow to tell: Water sits on the surface of the soil for a long time after you water. The bottom of the pot feels constantly cold and damp.
What to do: Switch to a pot with larger holes or add perlite to your soil mix to improve airflow. Never leave your fern sitting in a saucer full of water for more than 30 minutes.

When to worry
If the base of the plant is mushy and the fronds are collapsing, the damage is severe. It is normal for a few older fronds to die back as the plant grows.
Stopping it coming back
Water only when the top inch of soil feels slightly dry to the touch. Always use a light, airy soil mix that holds moisture without becoming dense.
