Establishment
First 6 monthsYoung plant developing root system and branch structure with sparse foliage
Plant in spring, ensure excellent drainage, provide bright light, keep in warm location (70°F+), minimal fertilizing
Vegetative Growth
1-2 yearsPlant develops multiple branches and elongated leaves, increasing in size and density
Water when top inch of soil is dry, apply balanced fertilizer monthly during growing season (May-September), provide full sun exposure
Pre-flowering
4-8 weeks before bloomBranch tips begin forming flower buds; leaves may cluster at branch ends
Transition to higher phosphorus fertilizer (e.g., 5-30-5), maintain consistent warmth and sunlight, reduce watering slightly
Flowering
3-6 months (typically May-October in northern climates)Fragrant flowers bloom in clusters at branch tips in shades of white, pink, red, yellow, or combinations; flowers last 1-2 weeks
Continue fertilizing every 2 weeks with bloom-promoting formula, maintain soil moisture (not soggy), deadhead spent flowers to encourage new blooms
Dormancy
October-February (3-4 months)Plant sheds leaves and enters rest period; branches become bare and woody
Drastically reduce watering (water only occasionally), stop fertilizing, keep in coolest location possible (50-60°F), allow dormancy for 2-3 months for optimal flowering next season

Harvest Tips
Plumeria is ornamental; flowers are harvested by hand for use in leis and arrangements. Pick flowers when fully open, cutting just below the flower cluster. Flowers last 1-2 days after cutting but are best enjoyed on the plant. Prune branches in late winter (while dormant) to shape plant and encourage branching.
Fun Facts
- 🌱 Plumeria flowers are deeply embedded in Hawaiian culture and are traditionally given as gifts to welcome visitors; white flowers symbolize grace while pink and red varieties represent love and passion.
- 🌱 The plant's latex sap can cause skin irritation in sensitive individuals, so gloves are recommended when handling stems or pruning.
- 🌱 Plumeria is deciduous and will shed all its leaves in winter as a natural dormancy mechanism; this is healthy behavior and not a sign of distress, though the bare branches may look alarming to new gardeners.
