Likely causes
Aphids
Most likelyHow to tell: You will see small green or black insects clustering on the fresh, soft growth at the tips of the vines. They often leave behind a sticky substance called honeydew.
What to do: Spray the plant down with a strong stream of water to knock them off. If they persist, apply insecticidal soap or neem oil every 5 to 7 days until they are gone.
Whitefly
PossibleHow to tell: These tiny white insects fly up in a cloud when you brush against the plant. Look for them hiding on the undersides of the leaves.
What to do: Use yellow sticky traps near the base of the plant to catch adults. Treat the foliage with insecticidal soap once a week for 3 weeks to break their life cycle.
