Regularly inspect Plumeria for signs of pests such as aphids, mealybugs, and scale insects. Treat infestations with horticultural oils or insecticidal soaps. Encourage beneficial insects and maintain good plant hygiene to reduce pest populations. Avoid using broad-spectrum pesticides that may harm beneficial insects and pollinators.

During the growing season, light pruning is recommended to shape Plumeria and remove dead or diseased growth. Trim spent flowers to promote new bud development. Avoid heavy pruning during this time, as it can reduce blooming and encourage excessive vegetative growth. Save major pruning for the dormant season.

During the growing season (spring and summer), water Plumeria when the top inch (2.5 cm) of the soil is dry. Provide enough water to thoroughly moisten the root zone, but avoid waterlogging. Plumeria prefers slightly drier conditions compared to excessive moisture. Overwatering can lead to root rot and other issues.
