Why does your Aloe broomii have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Scale insects attach themselves to the leaves of Aloe broomii and suck the sap, excreting a sugary substance known as honeydew which creates the sticky residue. This can lead to the growth of black sooty mold on the leaf surfaces.
Mealybugs are common pests for succulents like Aloe broomii; they feed on plant fluids and produce sticky honeydew as a byproduct. You may also notice white, cottony masses in the leaf axils.
Aphids congregate on tender new growth of the Aloe broomii, piercing the plant tissue to feed on sap and leaving behind sticky honeydew. This often results in distorted or curled leaf tips.
Some Aloe species possess extrafloral nectaries to attract predatory insects; while less common as a 'symptom,' an overproduction of nectar can feel sticky on the plant surface.
