Check these first

  1. Inspect the undersides of new leaves for clusters of small insects.
  2. Look for sticky residue on the foliage.
  3. Check stems for small, hard bumps.

Likely causes

  1. Aphid infestation

    Most likely

    How to tell: You will see clusters of tiny green or black insects on new stems and curled leaves. They often leave behind a sticky substance called honeydew.

    What to do: Spray the affected areas with a strong blast of water from your hose to knock them off. If they persist, apply insecticidal soap directly to the bugs every 5 to 7 days until they are gone.

  2. Scale insects

    Possible

    How to tell: These look like small, hard brown bumps on the stems or leaf veins. They do not move and can be scraped off with a fingernail.

    What to do: Prune away heavily infested branches to reduce the population. For lighter cases, dab the scale with a cotton swab dipped in rubbing alcohol.

A few aphids are normal in spring and usually handled by ladybugs. Worry only if the plant shows significant wilting or stunted growth.

Stopping it coming back

Encourage beneficial insects like ladybugs and lacewings to visit your garden by planting diverse native flowers nearby.
