Indian Borage · Plectranthus amboinicus

What are these white spots on my Indian Borage?

Mealybugs are the most common pest for Indian Borage, appearing as white, cottony clumps. Check the leaf axils where the leaves meet the stem to see if they are hiding there.

Check these first

  1. Look closely at the leaf joints for cottony white fluff.
  2. Check the undersides of leaves for tiny moving specks.
  3. Inspect the stems for fine webbing.

Likely causes

  1. Mealybugs

    Most likely

    How to tell: You see small, white, fuzzy masses on the stems or undersides of leaves.

    What to do: Dip a cotton swab in rubbing alcohol and dab it directly onto the pests. Repeat this every few days until they are gone.

  2. Spider Mites

    Possible

    How to tell: Tiny yellow stippling on leaves and very fine webbing between stems.

    What to do: Wipe the leaves down with a damp cloth to remove the webs. Increase humidity around the plant and spray with neem oil once a week.

When to worry

If the plant is covered in pests and the leaves are dropping, it is a serious infestation. A few bugs are easy to manage if you act quickly.

Stopping it coming back

Keep the leaves clean by wiping them occasionally and keep the plant away from other infested houseplants.
