Powdery Mildew

This is the most common fungal disease for Zinnias, caused by species like Podosphaera zinniae. It manifests as white, flour-like patches on leaves and stems, often triggered by high humidity and poor air circulation around the Dreamland foliage.

Mealybugs

These small insects secrete a white, waxy, cottony substance to protect themselves. They often cluster in the crevices of the leaf axils and stems of Zinnia plants, sucking sap and weakening the plant.

Cottony Scale

Certain scale insect species produce white, fluffy filaments that can resemble cotton. As they feed on the Zinnia's vascular system, they may cause leaf yellowing and stunted growth.
