blue flag

Blue Flag (Iris versicolor 'Bridesmaid') should be watered every 5-7 days during the summer months. During this time, water the soil deeply to ensure that it's moist but not soggy. During the spring and fall, the plant typically needs less water and should be watered every 10-14 days. During the winter months, reduce watering even further to about once a month. Be sure to check the soil periodically for moisture, and water when the top inch of soil feels dry.

Blue flag (Iris versicolor 'Bridesmaid') prefers full sun, but can also tolerate light shade in warmer climates (USDA Zones 3 - 8). This species prefers 5-6 hours of direct sunlight daily, especially when the temperatures are warmer. In more northern climates, blue flag varieties may benefit from some afternoon shade, as the intense afternoon sun can be too harsh. During the summer months, full sun is key to ensure healthy blooming.

Blue flag (Iris versicolor 'Bridesmaid') should be pruned in the late summer or fall when the foliage of the plant has started to die back. Pruning should be done carefully, with the goal of removing dead or diseased foliage and flower stalks while leaving as much of the healthy foliage as possible. Prune back flower stalks to within a few inches of the base of the plant, and remove any dead or diseased leaves or stems. Depending on the size of your Blue flag plant, you may need to divide and replant it every 3-4 years in the fall. This will help promote healthy growth.
