Dormancy/Rest
6-8 weeks (autumn/winter)Bulb is dormant, stored cool and dry or with minimal foliage. No active growth is occurring.
Store bulbs in a cool location (50-60°F) for 6-8 weeks to trigger blooming. Reduce watering almost completely. Do not fertilize.
Sprouting
2-3 weeksFlower buds and leaves begin to emerge from the bulb. A sturdy stem with developing flower buds becomes visible.
Place bulb in warm location (70-75°F). Begin regular watering. Place in bright light. Monitor for proper drainage to prevent rot.
Budding & Stem Elongation
2-3 weeksTall stems lengthen rapidly with 4-8 buds clustered at the tip. Leaves continue to develop alongside the stem.
Maintain consistent warmth and bright light. Water regularly to keep soil moist. Provide support stake if needed for tall varieties. Begin light fertilizing with balanced or high-phosphorus formula.
Flowering
4-6 weeksLarge, showy trumpet-shaped flowers open in succession on the stem, displaying vibrant colors. Each flower can measure 4-8 inches across.
Maintain bright light and moderate temperatures (65-75°F). Continue regular watering. Enjoy blooms for 2-3 weeks. Remove spent flowers to extend flowering period.
Vegetative Growth & Transition to Dormancy
4-6 monthsFlowers fade and leaves grow vigorously. Plant develops energy reserves in the bulb. Foliage remains green as leaves photosynthesize.
Maintain bright light and continue watering and fertilizing monthly to strengthen bulb for next season. Keep leaves healthy. Gradually reduce water as leaves naturally yellow and die back in summer/fall.

Harvest Tips
Cut flower stems when the first bud begins to crack open. Cut at a 45-degree angle with a sharp knife. Place in a vase with fresh, cool water and change water every 2-3 days. Remove lower leaves to prevent rot. Hippeastrum cut flowers typically last 1-2 weeks in a vase. For potted plants, leave foliage on the plant after flowering to regenerate the bulb for next season.
