Most likelyHow to tell: You will see tiny green or black insects clustering on new growth or flower buds. They often leave behind a sticky residue called honeydew.
What to do: Spray the plant with a steady stream of water to knock them off. If they persist, apply insecticidal soap once a week until they are gone.
Spider Mites
