Dormancy/Establishment
3-4 monthsFreshly planted rhizomes establish root systems in fall and winter with minimal visible foliage growth.
Water in at planting time; then water only during dry periods. Avoid overwatering which causes rhizome rot. Mulch lightly around (not over) the rhizome.
Spring Growth
4-6 weeksSword-like green foliage emerges and shoots upward as temperatures warm. Flower buds begin forming in the stems.
Remove any winter-damaged foliage. Apply balanced fertilizer as growth begins. Ensure good drainage to prevent rot. Stake tall stems if needed.
Flowering
3-4 weeksElegant ruffled flowers in peach and cream tones bloom on sturdy stems. Multiple buds per stem open in succession over several weeks.
Deadhead spent flowers to encourage more blooms on the stem. Tall varieties may need staking. Enjoy as cut flowers—they last 1-2 weeks in water.
Post-Bloom & Foliage
Summer through early fall (3-4 months)Flowers fade and plants focus on foliage growth and energy storage in rhizomes for next year. Leaves remain attractive throughout summer.
Continue watering moderately if weather is dry. Apply low-nitrogen fertilizer (higher potassium) to strengthen rhizomes. Trim dead flower stems at base.
Dormancy Preparation
Late fall to winter (2-3 months)Foliage gradually yellows and dies back as plants prepare for winter rest.
Reduce watering as foliage declines. Cut back dead leaves in late fall or early winter. Do not fertilize; avoid overwatering.

Harvest Tips
Cut flowers in early morning when stems are turgid. Harvest when the first bud is just opening for longest vase life. Cut stems at an angle just above a leaf node. Cherub Iris flowers last 1-2 weeks in clean water in a cool location. Deadhead spent blooms on garden plants to encourage secondary blooming. For division/rhizome harvest, wait until 3-4 weeks after flowering ends, then carefully dig and divide, ensuring each division has growing points and roots.
