Check these first

  1. Inspect the undersides of the leaves for clusters of insects.
  2. Check for sticky residue on the stems.
  3. Look for fine webbing between the leaf joints.

Likely causes

  1. Aphids

    Most likely

    How to tell: You will see small green or black insects clustered on the stems and new leaves. They often leave behind a sticky residue called honeydew.

    What to do: Spray the plant with a gentle stream of water to knock them off. If they persist, apply insecticidal soap once a week until they are gone.

  2. Spider Mites

    Possible

    How to tell: Look for fine webbing between the leaves and tiny yellow stippling on the foliage. These pests thrive in dry, hot conditions.

    What to do: Increase the humidity around your plant by misting it daily. Wipe the leaves down with a damp cloth to remove the mites and their webs.
