Dormancy & Root Development
4-8 weeksBulb is planted and begins establishing roots in cool soil over 4-8 weeks
Plant in fall (September-November) for spring blooming. Ensure excellent drainage. Mulch to protect from freezing.
Emergence & Vegetative Growth
6-8 weeksShoots emerge from soil in spring; tall stems develop with long, narrow leaves arranged in whorls
Stake tall varieties (3-8 feet) for support. Apply balanced fertilizer. Keep soil consistently moist. Remove any weak shoots.
Bud Formation
2-3 weeksFlower buds appear at stem tips; buds elongate and develop color
Continue staking as needed. Reduce nitrogen fertilizer; switch to phosphorus-rich formula to promote flowering. Water regularly.
Flowering
3-4 weeksLarge, fragrant trumpet-shaped flowers open, typically 4-8 blooms per stem; flowers last 1-3 weeks
Remove anthers to prevent pollen staining (if desired). Deadhead spent flowers but leave stem intact. Enjoy fragrance indoors or outdoors.
Post-Bloom & Dormancy
8-10 weeksFlowers fade; stems and foliage continue photosynthesis; bulb replenishes energy reserves
Do NOT cut stems yet; allow foliage to die back naturally (6-8 weeks). Continue watering and fertilizing. Once completely brown, cut to ground level.

Harvest Tips
Cut flowers when the first bloom on a stem is fully open or just showing color; cut in early morning for best vase life (7-10 days). Remove lower leaves that would sit below the waterline. Cut stems at an angle and refresh cuts every 2-3 days. For garden enjoyment, deadhead spent flowers but leave stems to nourish the bulb.
Fun Facts
- 🌱 Trumpet lilies produce very heavy pollen that can stain clothing and surfaces; removing the anthers extends vase life and prevents staining
- 🌱 Some trumpet lily varieties are highly fragrant especially in the evening, releasing volatile organic compounds that peak at specific times of day
- 🌱 The Easter Lily is actually a forced Lilium longiflorum; growers manipulate bulb chilling periods to make bulbs bloom on schedule for the holiday
