Bearded Iris
Iris germanica
Quick Care Guide
Prune: Remove spent blooms; cut back foliage after browning
Sunlight: Needs 6+ hours of full sun
Water: Water deeply when dry; drought-tolerant once established
Fertilize: Light feeding in early spring and after blooming
Leaves: Sword-shaped, upright, green to blue-green
Flowers: Showy blooms in spring; wide range of colors and patterns
Pruning
Bearded irises should be deadheaded after blooming to prevent seed formation and direct energy back to the rhizome. Cut the flower stalk down to the base once all flowers have faded. In late summer to early fall, trim the foliage to about 6 inches, especially if it becomes brown or diseased. This helps reduce pests and prepares the plant for winter.
Watering
Bearded irises are drought-tolerant once established and do best in well-draining soil. Water deeply during prolonged dry periods, especially in spring when they're actively growing. Avoid overwatering and soggy soil, which can lead to rhizome rot. Water at the base of the plant to keep foliage dry.
Leaves
The leaves are tall, upright, sword-shaped, and range from medium green to bluish-green. They add architectural interest even when the plant is not in bloom. Healthy foliage is key to feeding the rhizome for future flowering.
Sunlight
Bearded irises prefer full sun and need at least 6 hours of direct sunlight daily for optimal blooming. While they can tolerate light shade, too little sun may reduce flowering and increase the risk of fungal issues.
Fertilization
Apply a low-nitrogen fertilizer (such as 5-10-10) in early spring and again just after blooming. Avoid high-nitrogen fertilizers, which can promote excessive foliage at the expense of blooms and increase rot risk. Do not fertilize in late summer or fall.
Flowers
Bearded iris blooms are known for their ruffled petals, vibrant hues, and distinct “beards” on the lower petals (falls). Flower colors span the spectrum—purple, blue, white, yellow, pink, and even multi-colored varieties. Most bloom in mid to late spring, with some reblooming cultivars flowering again in late summer or fall.
