No matter where you live or what kind of plant you have, sooty mold may be the cause of unsightly black residue on the plants in your home or landscape. Sooty mold is a dull-black fungus that can grow on the leaves, fruit and stems of indoor and outdoor plants. The fungus is easy to identify by its âsootyâ appearance. Light infestations may begin at the base of leaves and move toward the tips. Heavy infestations can cause the entire plant to appear black. Sooty mold is caused by the presence of aphids, mealybugs, scale and whiteflies. These insect pests have mouthparts that suck plant juices, and as waste, they secrete a sweet substance known as honeydew. The honeydew lays on plant surfaces and over time grows into this specific mold.
