How do I get rid of pests on my fairy flax?

It is less common for fairy flax to get pests, which usually happens when the plant is stressed by poor air circulation or overcrowding. Check the undersides of the leaves first for any tiny webs or sticky residue.

Check these first

  1. Inspect the undersides of leaves with a magnifying glass.
  2. Look for sticky residue on the stems.
  3. Check for fine webbing between the leaves.

Likely causes

  1. Aphids

    Most likely

    How to tell: You will see tiny green or black insects clustering on the new growth. They leave behind a sticky substance called honeydew.

    What to do: Wash the plant gently with a soft stream of water to knock the insects off. Apply a mild insecticidal soap once a week until the pests are gone.

  2. Spider Mites

    Possible

    How to tell: Fine webbing appears between the leaves and stems. The leaves may look speckled or pale.

    What to do: Increase the humidity around the plant to discourage mites. Wipe the leaves down with a damp cloth and use neem oil if the infestation persists.
