Dormancy & Sprouting
3-4 weeksBulbs are planted in fall or early spring. Shoots emerge in spring as soil warms, with initial leaf growth appearing within 2-3 weeks.
Ensure bulbs are firm and disease-free before planting. Plant in fall (September-November) for best results. Keep soil consistently moist after sprouting begins.
Vegetative Growth
4-6 weeksTall stems with narrow, lance-shaped leaves develop rapidly. Plant reaches 2-3 feet in height with lush green foliage and visible flower buds forming at stem tips.
Provide sturdy staking or support, especially in windy locations. Apply balanced fertilizer (10-10-10) every 2-3 weeks. Maintain consistent moisture. Mulch around base to regulate soil temperature and retain moisture.
Budding & Pre-Bloom
2-3 weeksDistinctive buds appear at the stem apex and in leaf axils. Buds are green and elongated, gradually swelling as they prepare to open. Plant reaches full height of 3-4 feet.
Continue staking support. Reduce nitrogen fertilizer and switch to higher phosphorus formula (5-10-10) to encourage blooming. Maintain steady watering. Scout for pests and diseases.
Flowering
2-3 weeks per flower; overall flowering 3-4 weeksLarge, pure white trumpet-shaped flowers open in succession, each 6-8 inches long. Prominent golden stamens and intense, sweet fragrance. Multiple blooms per stem create spectacular displays.
Provide afternoon shade in very hot climates to extend bloom duration. Remove spent lower flowers as upper buds open. Do not remove flower buds or leaves. Deadhead only individual spent flowers, keeping stems intact for continued blooming.
Post-Bloom & Senescence
6-8 weeksFlowers fade and fall away. Stems and foliage continue to photosynthesize and green, storing energy back into bulbs for next season's growth.
Allow foliage to remain until it dies back naturally (6-8 weeks after flowering stops). Continue watering and feeding until leaves yellow completely. Cut stems only after they're entirely brown. Do not remove green leaves.

Harvest Tips
Cut stems in early morning when the first flower begins to open. Cut at least 1/3 of the stem length to ensure bulb energy recovery; do not remove more than 1/2 the stem. Cut flowers will last 10-14 days in a vase with fresh water and floral preservative. For garden viewing, deadhead spent flowers but allow stems to remain until fully brown. For bulb longevity, always allow foliage to remain until naturally senescent.
