Likely causes
Aphids
PossibleHow to tell: You see small green or black insects clustering on the tender new stems. They leave behind a sticky residue called honeydew.
What to do: Spray the stems with a gentle stream of water to knock them off. If they persist, use a mild insecticidal soap once a week.
Spider mites
PossibleHow to tell: Fine webbing appears between the stems and the plant looks dusty or mottled. This occurs when the air around the plant is too dry.
What to do: Increase humidity by misting the plant daily or placing it on a pebble tray. Wipe the stems down with a damp cloth to remove the mites.
