Black Bryony · Dioscorea communis

Why are there bugs on my Black Bryony?

It is less common for Black Bryony to get pests, but they can occasionally show up if the plant is stressed or kept in poor airflow. Check the undersides of the leaves first for any signs of movement or webbing.

Check these first

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

Likely causes

  1. Aphids

    Most likely

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

    What to do: Wipe the leaves down with a damp cloth to remove the bugs. Spray the plant with a mild insecticidal soap or neem oil every 5 to 7 days until they are gone.

  2. Spider Mites

    Possible

    How to tell: These pests create fine, dusty webbing between the stems and leaves. The leaves may start to look stippled or yellow as the mites feed.

    What to do: Increase the humidity around your plant, as mites hate moisture. Wash the foliage thoroughly with water and apply neem oil once a week for 3 weeks.

When to worry

Worry if you see the plant losing vigor or if the leaves start curling and dropping rapidly. A few stray bugs are manageable, but a full infestation requires immediate action.

Stopping it coming back

Keep your plant healthy with consistent watering and good air circulation. Regularly wipe the leaves with a damp cloth to keep them clean and dust free.

Questions people ask

Can I use dish soap to kill the pests?
Yes, but use a very mild, non-detergent soap mixed with water. Avoid anything with degreasers or heavy fragrances that might burn the leaves.
Will these pests spread to my other plants?
Yes, pests like aphids and mites move quickly between plants. Isolate your Black Bryony until you are sure the infestation is completely cleared.
