Why does your Begonia Havana Scarlet 8276 have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Aphids are small, soft-bodied insects that pierce the tender stems and leaves of Scarlet Begonias to suck sap, excreting a sugary substance known as honeydew. This residue creates the characteristic sticky film on the leaf surfaces.
Scale insects attach themselves to the Begonia foliage and feed on plant fluids, producing honeydew as a byproduct. Unlike aphids, these pests often look like small, stationary bumps or shells on the stems.
Whiteflies congregate on the undersides of Begonia leaves and excrete honeydew during feeding. A sudden cloud of tiny white insects may appear when you disturb the plant.
Mealybugs are slow-moving pests that produce sticky residue and often leave behind white, cottony masses in the leaf axils of the Begonia.
