Likely causes
Aphids
PossibleHow to tell: You will see tiny green or black insects clustering on the new growth. They suck the sap and cause the leaves to look distorted or yellow.
What to do: Spray the plant with a gentle stream of water to knock them off. If they persist, use a mild insecticidal soap once a week until they are gone.
Spider mites
PossibleHow to tell: Look for fine, silky webbing between the leaves and tiny yellow stippling on the foliage. These pests thrive in dry, warm environments.
What to do: Increase the humidity around your plant by misting it or using a pebble tray. Wipe the leaves down with a damp cloth to remove the mites and their webs.
