Why are there bugs on my Common camellia?

Seeing tiny insects on your camellia is common, but they can drain your plant's energy if left alone. Start by checking the undersides of leaves and along the stems for clusters of pests.

Check these first

  1. Inspect the undersides of leaves for tiny bumps or clusters.
  2. Check for sticky residue on the leaves or stems.
  3. Look for ants, which often farm aphids and scale.

Likely causes

  1. Scale insects

    Most likely

    How to tell: You will see small, brown, or white bumps that look like tiny shells attached to the stems or leaf veins. These do not move and are often mistaken for part of the plant.

    What to do: Scrape off light infestations with a soft toothbrush or your fingernail. For larger issues, spray the plant thoroughly with horticultural oil or neem oil every 7 to 10 days until they are gone.

  2. Aphids

    Possible

    How to tell: These tiny, soft, pear shaped insects cluster on the tender new growth and flower buds. They often leave behind a sticky substance called honeydew.

    What to do: Blast the aphids off with a strong stream of water from your garden hose. If they persist, apply insecticidal soap directly to the affected areas once a week.

When to worry

Worry if you see sooty mold forming on the leaves, as this indicates a heavy infestation that needs immediate treatment. A few stray bugs are usually manageable with a quick wash.

Stopping it coming back

Keep your camellia healthy with proper watering and airflow to make it less attractive to pests. Check your plant every few weeks during the growing season to catch issues early.

Questions people ask

Will these bugs kill my camellia?
A light infestation usually will not kill a mature plant, but it can weaken it and cause poor flowering. Heavy, untreated infestations can cause significant leaf drop and branch dieback.
Can I use household soap to kill them?
Avoid using harsh dish soaps, as they can burn the leaves. Stick to insecticidal soaps or horticultural oils specifically formulated for garden use.
