Disease or Pest Infestation

Finally, yellowing leaves on impatiens can also be a sign of disease or pest infestation. Common pests that affect impatiens include spider mites, aphids, and whiteflies. These pests can damage the plant's leaves, causing them to yellow and fall off. Additionally, diseases like powdery mildew and downy mildew can also cause the leaves to discolor and die.
