Soil Type

Water: Thriving in swampy habitats, zigzag iris tolerates moisture and brief dry spells. It prefers consistent moisture and should be watered weekly. As an herbaceous perennial, zigzag iris can withstand temporary flooding, making it ideal for rain gardens or fluctuating water levels.

Fertilize: Fertilize zigzag iris with balanced nutrition in early spring as growth begins, using half-strength monthly. Avoid over-fertilization, especially during dormancy in fall and winter. Apply when soil is moist to prevent root burn and enhance nutrient absorption for better foliage and blooms.

Pruning: Zigzag iris is a hardy, low-maintenance flowering plant with zigzag stems. Prune from early to late spring, removing dead foliage and spent blooms to promote growth. Cut back old stems post-blooming, enhancing vigor and air circulation while using sterile tools to prevent infection.

Propagation: Native to North America, zigzag iris thrives in moist areas and spreads clonally. Propagation is mainly through division, ensuring roots and leaf fans, while cuttings can root with proper warm, moist conditions. Proper handling and suitable site selection enhance establishment and growth.
