While there are no specific Plumeria cultivars known to be completely immune to diseases, some cultivars may exhibit better disease resistance compared to others. Factors such as climate, growing conditions, and overall plant health also influence disease susceptibility. Generally, cultivars with robust growth, strong root systems, and good overall vigor are more likely to withstand and recover from disease pressures. Proper cultivation practices, including providing adequate sunlight, well-draining soil, and regular inspections for signs of disease, are essential for maintaining the health and vigor of Plumeria cultivars, regardless of their disease resistance levels.
