Soil Type

Water: Adapted to moderate moisture, white-flowered iris thrives with consistent weekly watering to prevent waterlogging. While it benefits from natural rainfall outdoors, supplemental irrigation is necessary during prolonged dry spells or in arid climates.

Fertilize: White-flowered iris thrives in humus-rich soil, requiring fertilization in early spring, early fall, and prior to blooming. Use phosphorus-rich (5-10-5 NPK) or balanced (20-20-20 NPK) fertilizers. Organic options may enhance soil quality. Water immediately after fertilizing to aid nutrient absorption.

Pruning: Prune white-flowered iris in early to late spring to remove dead foliage and spent stalks, promoting healthy growth and disease prevention. Regular pruning enhances air circulation and aesthetics. Use clean, sharp tools for precise cuts to achieve optimal results.

Propagation: White-flowered iris can thrive through vegetative propagation using tubers, a method favored by gardeners for ease and effectiveness. Proper soil preparation and consideration of environmental factors are crucial for optimal root establishment and plant health.
