Variegated Sweetheart Hoya pests — FAQ
What is eating my variegated sweetheart hoya?
Variegated Sweetheart Hoya (Hoya kerrii 'Variegata') is a slow-growing houseplant most troubled by mealybugs hiding at the base of the thick heart-shaped leaf and along any developing stem. Spider mites and scale are also recorded on Hoya kerrii. The low-chlorophyll variegated form is especially vulnerable because slow growth delays recovery.
