Yes, Plumeria plants have some degree of drought tolerance due to their semi-succulent nature. They can survive periods of low water availability by drawing on stored moisture in their thick stems and roots. However, while Plumeria can tolerate drought, it is still essential to provide sufficient water, especially during the active growing season when the plant is producing flowers. Regular watering ensures healthy growth and flower development, even in regions with seasonal droughts. For container-grown Plumeria, ensuring proper drainage helps prevent waterlogged soil and root rot.
