Lady fern · Athyrium filix-femina

Why are my Lady fern's leaves turning yellow?

Yellowing fronds often signal that your fern is getting too much water or not enough light. Check the soil drainage first to make sure the roots are not sitting in water.

Check these first

  1. Check if the soil is waterlogged or swampy.
  2. Assess the light levels in the current location.
  3. Look for signs of pests on the underside of the leaves.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The fronds turn yellow and feel limp or mushy. The soil stays wet for a long time after watering.

    What to do: Let the top inch of soil dry out before watering again. Ensure your pot has drainage holes so excess water can escape.

  2. Too much light

    Possible

    How to tell: The fronds look bleached or pale yellow rather than a deep green. This happens when the fern gets direct sun instead of the shade it prefers.

    What to do: Move the plant to a spot with partial or full shade. Avoid windows that get direct afternoon sun.

When to worry

A single yellow frond at the base is usually just an old leaf dying off. If multiple fronds turn yellow at once, the plant is stressed.

Stopping it coming back

Use a well-draining potting mix and always check the soil moisture before adding more water.

Questions people ask

Can I save a yellow frond?
Once a frond has turned fully yellow, it will not turn green again. It is best to remove it so the plant can focus energy on new growth.
Is yellowing a sign of fertilizer burn?
It can be if you have over-fertilized. Lady ferns are light feeders, so only use a balanced fertilizer at half strength once in the spring.
