Do not leave cuttings in mist beds for excessive periods. Pot as soon as rooted. Leaf and Flower Gall Young leaves and flowers become swollen, fleshy, and pale-green. These become white due to the formation of spores by the fungus on the surface. Later, the galls become hard and brown.
Infection occurs in the spring.
The new spores formed on the surface of the galls are dispersed but do not cause more galls to form during that same season. They remain dormant until the following spring. Exobasidium vaccinii Remove and destroy all galls before they become white with new spores. If many plants had the disease in previous years and galls were too numerous to pick, apply a fungicide to protect new foliage and flowers as they emerge. Applications can cease when the leaves reached their full size.
