Bulb Dormancy
12-16 weeksBulbs are planted in fall and require 12-16 weeks of cold temperatures (below 55°F) to initiate flowering.
Plant in autumn (September-November) at proper depth. Ensure soil drains well to prevent rot. Mulch lightly to protect from extreme cold.
Emergence
2-3 weeksShoots break through soil in early spring as temperatures warm, with green leaves unfurling.
Remove mulch as growth begins. No fertilizer needed; bulbs contain stored nutrients. Monitor for excessive moisture.
Vegetative Growth
3-4 weeksSturdy stems develop with elongated blue-green leaves; flower buds form within the foliage.
Provide full sun for strong stem development. Water if spring is particularly dry. Support tall stems if exposed to wind.
Flowering
1-2 weeks per flowerLarge cup-shaped flowers with orange-red petals and deep purple flames open in mid-spring (April-May in most regions).
Enjoy fresh blooms in garden or cut for arrangements. Deadhead spent flowers but leave stems and leaves intact to support bulb regeneration.
Post-Bloom & Dormancy
6-8 weeksLeaves yellow and die back after flowering; bulbs enter dormancy. Energy transfers to bulb for next season.
Leave foliage in place for 5-6 weeks after flowering to allow photosynthesis. Gradually reduce watering. Apply low-nitrogen fertilizer if desired. Remove dead leaves when completely brown.

Harvest Tips
Cut flowers in early morning when buds are just opening for longest vase life. Cut stems at a 45-degree angle and place immediately in cool water with floral food. Tulips continue opening in the vase and can last 7-14 days. For garden display, deadhead spent flowers but leave stems and foliage to feed the bulb for next year's blooms.
