Why are there bugs on my Southern dewberry?

Seeing tiny insects clustering on your dewberry is common, especially on new, tender growth. Most often, these are aphids that feed on the plant's sap. Check the undersides of the leaves to confirm their presence.

Check these first

  1. Inspect the undersides of the leaves for clusters of small insects.
  2. Look for sticky honeydew or fine webbing on the stems.
  3. Check if the new growth is curling or stunted.

Likely causes

  1. Aphid infestation

    Most likely

    How to tell: You will see small, soft bodied insects clustered on the stems and undersides of leaves. They often leave behind a sticky residue called honeydew.

    What to do: Spray the plant with a strong stream of water to knock them off. If they persist, apply insecticidal soap or neem oil directly to the affected areas every 5 to 7 days.

  2. Mite activity

    Possible

    How to tell: Look for fine webbing between leaves or stems. The foliage may appear stippled or pale.

    What to do: Increase humidity around the plant if possible. Use a miticide or neem oil spray to treat the infestation thoroughly.

When to worry

Small numbers of aphids are usually manageable, but you should worry if the plant shows signs of stunted growth or heavy leaf curling. A few bugs are normal in an outdoor garden.

Stopping it coming back

Keep your dewberry healthy with proper watering and sunlight to help it resist infestations. Regularly inspect new growth during the spring months.
