Aphids
PossibleHow to tell: You will see tiny green or black insects clustering on the new growth or flower stalks. 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.
Spider Mites
PossibleHow to tell: Look for fine webbing between the stems and tiny yellow stippling on the leaves. These pests thrive in dry, hot conditions.
What to do: Increase the humidity around your plant by misting it or moving it to a cooler spot. Wipe the leaves down with a damp cloth to remove the mites and their webs.
