Common asparagus fern · Asparagus setaceus

Why are my asparagus fern's leaves turning yellow?

Yellowing foliage on your asparagus fern usually signals that the plant is unhappy with its environment or moisture levels. Check the soil moisture first to see if you are overwatering or if the plant is simply too dry.

Check these first

  1. Feel the top inch of soil for dampness.
  2. Inspect the undersides of the leaves for tiny webs.
  3. Check if the pot is sitting in standing water.

Likely causes

  1. Overwatering

    Most likely

    How to tell: The leaves turn yellow and feel soft or mushy to the touch. The soil stays wet for more than a week.

    What to do: Stop watering immediately and let the top 2 inches of soil dry out. Ensure your pot has drainage holes so excess water can escape.

  2. Spider Mites

    Possible

    How to tell: You see tiny yellow speckles on the needles and fine webbing between the stems. These pests love dry indoor air.

    What to do: Wipe the foliage down with a damp cloth to remove the mites. Increase humidity around the plant by misting it daily or using a pebble tray.

When to worry

Stopping it coming back

Maintain a consistent watering schedule and keep the air around your fern humid to discourage pests.
