Dormancy/Bare Branching
December to March (3-4 months)Plant loses most or all leaves during winter; branches appear bare and grayish. This is normal and healthy for plumeria.
Reduce watering significantly. Withhold fertilizer. Keep in cool (50-65°F) location. Do not panic—leaves will return in spring.
Leaf Emergence & Vegetative Growth
March to May (6-8 weeks)New reddish or bronze leaves emerge at branch tips in spring; plant begins rapid growth with new stem extension.
Increase watering gradually. Begin feeding with balanced fertilizer or plumeria-specific formula. Ensure bright light. Prune any weak or crossing branches.
Bud Formation
April to June (4-8 weeks)Dense clusters of flower buds form at branch tips; buds are tight and waxy, gradually enlarging and showing color.
Maintain consistent watering and full sun exposure. Switch to higher-phosphorus fertilizer to support flowering. Avoid overfeeding with nitrogen, which promotes foliage over flowers.
Flowering
June to September (3-4 months)Large, fragrant white flowers with creamy yellow centers open in clusters. Flowers are 2-3 inches across and bloom continuously.
Maintain steady moisture; do not let soil dry completely. Continue phosphorus-rich feeding every 2 weeks. Remove spent flower clusters to encourage new buds. Enjoy the intense, sweet fragrance.
Post-Bloom & Hardening Off
September to November (2-3 months)Flowering slows as days shorten and temperatures cool. Plant begins to transition toward dormancy; leaf growth may slow.
Gradually reduce watering. Begin tapering fertilizer in late August. Bring container plants to protected location before first frost. Remove any diseased or weak growth.
