Thanks for contacting us about your hawthorn. Hawthorn mealybugs can be difficult to manage or control with foliar (spraying leaves) treatments. These insects have a waxy covering (the white stuff) that protects them well. See the link below for details on what to treat them with, when to treat them, and how to control their return next year.
