Plant Bernice's Legacy Bearded Iris in well-drained soil with full sun exposure. Space rhizomes 12-24 inches apart, ensuring the top is exposed to sunlight. Water thoroughly after planting, then water sparingly, allowing soil to dry between waterings. Fertilize in early spring with a low-nitrogen fertilizer. Remove spent blooms to encourage more flowers. Divide clumps every 3-4 years in late summer to prevent overcrowding.
