Bulb Dormancy & Cold Treatment
12-16 weeks (September-December)Bulbs are planted in fall and require 12-16 weeks of temperatures below 45°F (7°C) to break dormancy and initiate flowering.
Plant bulbs immediately upon receipt. Ensure soil stays cool and dry during winter. Mulch with 2-3 inches of organic matter for insulation. No watering needed during this period.
Emergence & Growth
2-3 weeksAs soil warms in early spring, shoots emerge and develop. Leaves unfurl, typically appearing in late March to early April depending on climate.
Water moderately if spring is dry. Remove mulch as shoots emerge to allow light penetration. Apply balanced bulb fertilizer (5-10-10) at emergence.
Bud Development & Flowering
3-4 weeksFlower buds form and develop, with blooms opening 2-3 weeks after emergence. Flowers are brilliant crimson-red, cup-shaped, and typically last 2-3 weeks.
Water regularly during bloom if rainfall is insufficient. Deadhead faded flowers to prevent seed formation and conserve energy. Avoid excessive fertilizer, which promotes foliage at the expense of flowers.
Foliage Development & Nutrient Repletion
4-6 weeksAfter flowering ends, foliage continues to photosynthesize and replenish bulb reserves. Leaves remain green and functional for several weeks.
Allow foliage to remain until it yellows naturally (do not cut or tie back early). Continue watering until foliage dies down. Apply low-nitrogen bulb fertilizer (5-10-10) to support bulb development.
Dormancy & Senescence
June-SeptemberFoliage yellows and dies back completely; bulbs enter dormancy in early summer and remain inactive until fall replanting.
Stop watering once foliage is completely brown. Bulbs can be left in the ground or lifted and stored in a cool, dry location (50-60°F) in peat moss or sand until replanting.
