Ideal time to plant plumeria: set it out when the soil is neither frozen nor waterlogged, and water generously as it establishes.

Expert tips
The key tip
Le frangipanier a besoin d'une vraie dormance hivernale pour fleurir: arrêtez l'eau complètement dès novembre et gardez-le au sec et frais (10-15°C si possible) jusqu'en mars. C'est durant cette phase que se forment les boutons floraux. Sans repos, vous aurez un buisson feuille mais zéro fleur.
The common mistake
Arroser régulièrement toute l'année tue le frangipanier. La plupart des jardiniers continuent à l'arroser l'hiver comme une plante normale, ce qui provoque la pourriture racinaire et la chute des feuilles.
The pro's trick
Pincez les rameaux en mai-juin après la sortie du repos. Cette taille légère force la branchification et multiplie les points de floraison: vous aurez deux fois plus de grappes de fleurs l'été suivant sans fatiguer la plante.
Seasonal watch
En fin d'été (septembre), réduisez graduellement les arrosages pour préparer la dormance. Un apport d'eau trop tardif à l'automne repousse la floraison et affaiblit la plante avant l'hiver. Observez la base des feuilles: dès qu'elles commencent à jaunir, c'est le signal d'arrêter.
Care
Light exposure
Plumeria demands maximum direct sunlight to flower abundantly. Place it in a very bright location, ideally facing south or west. Insufficient light drastically reduces flowering and overall vigor.
Watering
Water regularly during the growing season (spring-summer), allowing the substrate to dry between waterings. In autumn and winter, reduce watering significantly, especially if temperatures drop. Excess moisture promotes root rot.
Soil and substrate
Use a light, well-draining mix: flowering plant potting soil enriched with perlite or sand. Plumeria hates stagnant moisture and heavy soils. Good drainage is essential to prevent fungal diseases.
Fertilizing
During the growing season (spring-summer), apply balanced or phosphorus-rich fertilizer every 2 to 3 weeks to support flowering. Stop fertilizing entirely in autumn-winter during the dormant period.
Pruning and maintenance
In late winter, lightly prune branches to encourage a compact, well-branched shape. Remove dead or weak wood. Severe pruning harms the current year's flowering.
Diseases and pests
Watch for mealybugs and spider mites, especially indoors. Root rot is the main risk if watering is excessive. Ensure good air circulation around the plant and avoid wetting the foliage to prevent fungal diseases.
Did you know?
Plumeria is a sacred symbol in Southeast Asia, notably in Thailand and Cambodia, where its white and pink flowers are offered in temples. In Hawaii, the plumeria lei (flower garland) is an unmissable cultural emblem, associated with beauty and aloha, the spirit of island hospitality.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
