Q.My Schfflera Plant Has Developed Sticky Leaves. I Have Also Seen A Drop Of Liquid Between Stems. I Wiped Each Leaf Off But The
sticky material came back. This Schfflera plant is located indoors with adequate lighting. IT IS ABOUT 5 feet tall and is watered only when the soil is dry to the touch. Why are leaves becoming sticky? I wiped each leaf off with water and dried them, but the sticky situation returned on most of the leaves.

Check the undersides of the leaves for aphids. They leave a sticky residue called honeydew. If you don't see them, check the stems for scale insects such as mealybugs.
