Pest Alert: Scale Insects on Holly
Hollies are generally tough, pest free plants. However they can have some issues. One of the most common issues on hollies here in Henderson County is scale insects.
Scale insects can be found feeding on the back sides of the leaves of hollies. These sucking insects use a needle-like mouth-part to pierce leaves and drink the sugary sap inside. Scale insect droppings are sugary and drip onto the upper surfaces of leaves below. A black fungus called sooty mold grows on the droppings.
