Marginal wood fern · Dryopteris marginalis

Why are my Marginal wood fern's leaves turning yellow?

Yellowing fronds often point to issues with how you are watering or the light the plant receives. Check the soil moisture level first to see if it is soggy or bone dry.

Check these first

  1. Check if the soil is soggy or waterlogged.
  2. Assess the light levels in the current location.
  3. Look for signs of root rot.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The fronds turn yellow and soft, and the soil stays wet for a long time. You might notice a musty smell coming from the pot.

    What to do: Stop watering immediately and let the top inch of soil dry out. Ensure the pot has good drainage and never let the plant sit in standing water.

  2. Too Much Light

    Possible

    How to tell: The fronds look bleached or washed out rather than a deep green. This happens if the plant is getting too much direct sun.

    What to do: Move the fern to a spot with partial to full shade. It prefers medium light and will suffer if exposed to direct sun.

When to worry

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

Stopping it coming back

Stick to a consistent watering schedule and keep the plant in a shaded area away from harsh light.
