Here’s a guide to watering ‘Queen’s Circle’ irises effectively:

Establishment: After planting ‘Queen’s Circle’ irises, ensure adequate moisture to help them establish their root systems. Water deeply immediately after planting, and continue to provide consistent moisture in the following weeks.
Spring Growth: As the irises emerge in spring and begin active growth, maintain even soil moisture. Avoid waterlogged conditions, but do not allow the soil to dry out completely.
Blooming Period: During the blooming period, consistent moisture is vital to support the development of robust flowers. Water ‘Queen’s Circle’ irises regularly, especially during dry spells, to promote healthy blooms.
Summer Dormancy: After the blooming period, ‘Queen’s Circle’ irises enter a period of dormancy. While they are more tolerant of dry conditions during this time, occasional deep watering can support the development of new rhizomes.
