Dormancy & Root Development
6-8 weeksBulbs planted in fall develop roots during winter while leaves remain underground. Minimal visible growth occurs above soil.
Plant bulbs in well-prepared soil in October-November. Ensure soil drains well to prevent rot. Mulch lightly after ground freezes to regulate temperature.
Emergence & Vegetative Growth
3-4 weeksGreen shoots emerge in early spring as soil warms. Leaves unfurl and the flowering stem extends upward.
Remove winter mulch as growth begins. Monitor for slugs and snails. Water if spring is dry. Provide support in windy locations.
Budding & Pre-Bloom
1-2 weeksThe flower bud forms at the stem tip and begins to swell. The characteristic cup shape becomes visible as the bud elongates.
Ensure consistent moisture. Avoid overhead watering to prevent petal damage. Stake tall stems if needed.
Flowering & Bloom Peak
7-10 daysPure white, large cup-shaped flowers open fully. Flowers are at their largest and most fragrant.
Pinch off flowers after 5-7 days if using for cut flowers to extend vase life. Deadhead spent blooms if leaving bulbs in ground.
Post-Bloom & Foliage Decline
4-6 weeksPetals drop and leaves begin to yellow as the plant channels energy back into the bulb for next year.
Do NOT cut foliage until it dies back naturally (4-6 weeks after bloom). Continue watering to feed the bulb. Remove spent flower stalks.

Early Spring Pollinator Support
WildlifeProvides pollen and nectar for bees and other pollinators as one of the earliest spring bulbs to bloom, supporting wildlife during critical early season foraging. [source]
Harvest Tips
Cut tulips in early morning when stems are fully turgid. Cut stems at a 45-degree angle just above the soil line or lower foliage leaves. Cut when flowers are still in bud or just opening for longest vase life (7-12 days with proper care). Immediately place cut stems in clean, cool water with flower food. Change water every 2 days. For garden bulbs, deadhead spent flowers but leave stems and foliage to die back naturally to support next year's blooms.
