WHAT TO DO

Frangipani/Plumeria Rust: This disease causes yellow spots and premature leaf drop but does not affect the long-term health of the plant. Removing, raking, and disposing of infected leaves may slow the infection.

Irrigation: Irrigate if the weather has been warm and dry. Monitor plants for signs of stress and water only as needed.
