watering
Water blue flag Iris plants regularly but not too heavily. Water enough to keep the soil evenly moist throughout the growing season, meaning once or twice a week during warm weather. Be sure to saturate the soil thoroughly, but avoid soggy conditions which can lead to root rot. During times of heavy rains, there may be no need to water. These Iris respond well to supplemental watering during periods of drought or in plantings located in hot, dry areas. After the blooms have died, reduce watering until the following spring.
sunlight
Blue flag (Iris versicolor 'Whodunit') requires full sunlight for at least 4 to 6 hours per day. This is the ideal sunlight requirement for a vigorous growth and strong blooms. If these conditions are met, its deep-purple and white blooms can appear as early as April and will last until August. In the shade, blue flag may bloom but not as profusely or persistently as in direct sunlight. If the plant does not get enough sunlight, its blooms may be few and sparsely spread. An additional 2 to 3 hours of sunlight per day can help enhance its blooming.
pruning
Blue flag (Iris versicolor 'Whodunit') should be pruned 2 times a year. Prune in early spring, cutting the old foliage to the ground. This encourages healthy new growth in the spring. Then, in late summer, cut back new growth by half, just above a leaf node. This helps control the size of the plant and promotes more blooms for the next season.
