Why does your Lilium Relucida have white cottony spots? Diagnose the cause and fix it with our step-by-step guide.
Mealybugs are small, soft-bodied insects that secrete a white, waxy, cottony substance to protect themselves. They attach to the nodes and undersides of Lilium relucida leaves, sucking sap and weakening the plant.
This fungal disease manifests as white, flour-like patches on the leaf surface. In Lilium relucida, high humidity and poor air circulation around the foliage often trigger spore germination.
Botrytis can cause grayish-white, fuzzy patches on lily petals and leaves, especially in damp conditions. It often begins as small spots that expand into a moldy, cottony mass during humid nights.
Similar to mealybugs, woolly aphids produce a white, flocculent coating on their bodies and can cluster on young Lilium relucida shoots. Their presence often leads to the secretion of honeydew, which may cause black sooty mold.
