Dormancy
2-4 monthsPlant loses all leaves and enters complete rest period, typically December-February in Northern Hemisphere. Branches appear bare and woody.
Reduce watering to minimal amounts; provide no fertilizer; keep plant in cool, dry location; do not be alarmed by leaf loss
Bud Break & Leafing
3-4 weeksNew leaves emerge from branch tips in early spring, initially reddish or bronze before turning green. Plant begins active growth.
Increase watering gradually; begin monthly diluted fertilizer; ensure strong light; prune if shaping is needed
Vegetative Growth
4-8 weeksPlant produces abundant green foliage on branching stems. Leaves are long, narrow, and clustered at branch ends. No flowers yet.
Water regularly when soil surface is dry; fertilize every 2-3 weeks with balanced or slightly higher phosphorus formula; remove any crossing branches
Flowering
4-8 weeks or longerFragrant flower clusters (inflorescences) appear at branch terminals. Each flower is 2-3 inches across with 5 petals, typically red or pink with yellow/white centers.
Continue regular watering and fertilizing with phosphorus-rich formula; provide maximum sunlight; deadhead spent flowers to encourage more blooms; do not move flowering plant
Post-Flowering & Dormancy Transition
4-6 weeks into dormancyFlowering slows as days shorten and temperatures cool. Plant begins to lose leaves gradually. Growth slows significantly.
Reduce watering gradually; reduce fertilizer frequency; allow natural dormancy to begin; do not attempt to force continued growth

Harvest Tips
Plumeria is grown for ornamental flowers rather than harvest. Cut flower clusters when blooms are fully open for floral arrangements; they last 5-7 days in water. Collect seeds from pod-shaped fruits (rarely produced in cultivation) if you wish to grow new plants. Cuttings are best taken in spring and should be allowed to callus for 1-2 weeks before planting.
Fun Facts
- 🌱 Plumeria rubra is the national flower of Nicaragua and is also an important flower in Hawaiian culture, where it is called 'Melia' and used exclusively in lei-making for centuries.
- 🌱 The plant's flowers are strongly night-fragrant, meaning they release their most intense, sweet scent during evening and early morning hours to attract night-feeding moths as pollinators.
- 🌱 Plumeria stems contain a milky white latex sap that can cause skin irritation in sensitive individuals, so gloves are recommended when handling cuttings or pruning branches.
