Growth Stages
Dormancy & Planting
3-4 weeks after planting (spring emergence) or entire winter (fall planting)Bulb is dormant underground. Ideal planting window is fall (September-November) or early spring (March-April) when soil is workable.
Choose large, healthy bulbs (10-12 cm circumference for Casa Blanca). Ensure excellent drainage to prevent rot during dormancy. Apply mulch in fall in colder zones.
Emergence & Vegetative Growth
4-6 weeksGreen shoots emerge from soil in spring. Stems grow rapidly, developing narrow, lance-shaped leaves arranged along the stem.
Provide consistent moisture. Apply balanced fertilizer (10-10-10) as shoots emerge. Mulch around base to retain moisture and suppress weeds. Stake tall varieties if planted in windy locations.
Bud Formation & Elongation
3-4 weeksBuds appear at stem tips and along upper portion of stem. Stems continue growing to full height (3-5 feet). Buds swell and elongate.
Continue consistent watering. Apply high-potassium fertilizer (e.g., 5-10-10) to promote strong stems and large blooms. Remove any diseased leaves. Stake plants if necessary.
Flowering
3-4 weeksLarge, pure white trumpet flowers open sequentially over 2-3 weeks. Each flower lasts 3-7 days; powerful sweet fragrance fills the garden. Up to 10-15 blooms per stem on mature plants.
Avoid touching petals to prevent pollen stains and extend bloom life. Remove stamens if keeping for indoor arrangements (reduces pollen and extends vase life). Deadhead spent flowers but leave stems standing. Reduce watering slightly.
Post-Bloom & Senescence
6-8 weeksFlowers fade and wilt. Seed pods may develop if flowers weren't removed. Foliage remains green and provides energy to bulb for next season.
Remove dead flower heads but leave green stems and foliage intact until they yellow naturally (6-8 weeks post-bloom). Continue light watering. This period is critical for bulb regeneration—don't cut foliage prematurely. Allow stems to die back naturally before removing.
Common Pests
-
Hand-pick beetles and larvae in early morning; remove affected leaves; use neem oil or spinosad; encourage natural predators; remove plant debris in fall where eggs overwinter
-
Spray with water to dislodge; use insecticidal soap; apply neem oil; encourage ladybugs and lacewings
-
Increase humidity by misting foliage; apply miticide spray if severe; remove heavily infested leaves
-
Improve air circulation; avoid overhead watering; remove infected leaves promptly; apply fungicide if severe; thin overcrowded plantings
-
Ensure excellent drainage; amend soil with sand/perlite; don't overwater; treat with fungicide if caught early; replant in new location if severe
-
No cure; remove and destroy infected plants; control aphids to prevent spread; plant in isolation if growing multiple lilies; sterilize tools between plants

Harvest Tips
Cut flowers when the first bud on the stem begins to open or show color. Cut in early morning with a sharp knife, cutting stems at an angle. Leave at least 2-3 sets of leaves on the plant to feed the bulb. Flowers will continue opening indoors. For arrangements, remove stamens with tweezers to prevent pollen stains and extend vase life (7-14 days). Change water every 2-3 days. Do NOT cut foliage after blooming ends until it yellows naturally—this energy is essential for next year's blooms.
