What are the pests on my Wood sage?

It is less common for Wood sage to suffer from severe pest infestations, as its aromatic leaves often deter many insects. The most common issue is aphids, which usually appear when the plant is stressed by drought or poor airflow.

Check these first

  1. Inspect the undersides of leaves for tiny insects or webbing.
  2. Check the new growth tips for clusters of aphids.
  3. Look for sticky residue on the foliage.

Likely causes

  1. Aphids

    Most likely

    How to tell: You will see clusters of tiny green or black insects on the undersides of leaves or near the new growth tips. They often leave behind a sticky substance called honeydew.

    What to do: Spray the affected areas with a strong stream of water to dislodge the insects. If they persist, apply insecticidal soap or neem oil every 5 to 7 days until they are gone.

  2. Spider Mites

    Possible

    How to tell: Look for fine, dusty webbing between the leaves and tiny yellow stippling on the foliage. These pests thrive in hot, dry conditions.

    What to do: Increase the humidity around the plant by watering the soil consistently. Wipe the leaves down with a damp cloth and apply neem oil to the undersides of the leaves once a week.

When to worry

Small numbers of aphids are usually manageable, but you should act if you see the plant's growth stunting or leaves yellowing. It is normal to see an occasional stray insect in a garden setting.

Stopping it coming back

Keep the plant healthy with consistent watering and ensure good airflow to prevent pest buildup.
