Propagation/Rooting
3-4 weeksHardwood cuttings developing root systems over 3-4 weeks in well-draining medium
Use 6-8 inch cuttings from mature wood, allow to callus 24-48 hours before planting. Maintain warm conditions (70-80°F). Bottom heat aids rooting. Keep soil barely moist, not wet.
Establishment
2-3 monthsYoung plant developing foliage and stronger root system, 6-12 inches tall
Gradually acclimate to full sun. Water when dry. Begin light fertilizing once growth is vigorous. Protect from cold drafts.
Vegetative Growth
6-12 monthsPlant develops leafy branches and increases in size, typically 1-3 feet per year in ideal conditions
Full sun exposure is essential. Feed monthly during warm season with balanced or flowering fertilizer. Prune to shape and encourage branching. Maintain consistent watering during growing season.
Flowering
2-4 months (spring through fall)Terminal clusters of large, fragrant flowers appear at branch tips; flowers are pink-red with yellow centers
Flowers develop on new growth. Ensure full sun and adequate phosphorus/potassium in fertilizer. Each flower lasts 1-2 days but blooms continuously for weeks. Deadhead spent flowers to encourage more blooms.
Dormancy
2-3 monthsPlant drops leaves in fall/winter and enters rest period with minimal growth
Dramatically reduce watering; allow soil to dry out completely between rare waterings. Withhold fertilizer. Plant can tolerate cooler temperatures (50-60°F) but prefers warmth. Resume normal care in spring.

Harvest Tips
Plumeria is an ornamental plant grown for flowers, not harvested in traditional sense. Cut blooms for arrangements by snipping at the base of flower clusters; they last 1-2 days in water but provide exceptional fragrance. Harvest seeds from mature seed pods (if setting) in late fall by allowing pods to dry on plant, then collecting and drying further.
