Yes, some Plumeria diseases can be transmitted through airborne spores. One common disease that can be spread this way is Plumeria Rust (Coleosporium plumeriae). This fungal disease produces rust-colored pustules on the undersides of Plumeria leaves. When these pustules burst, they release countless spores into the air. If nearby healthy Plumeria plants come into contact with these spores, they can become infected.

To prevent the spread of diseases like Plumeria Rust, it’s essential to promptly remove and dispose of infected leaves and provide good air circulation around your Plumeria plants. Additionally, using fungicides as a preventive measure during the growing season can help reduce the risk of airborne spore transmission. Regularly inspecting your plants for signs of disease and taking action when needed is key to keeping your Plumeria healthy.
