How to Grow Bearded Irises in Containers

Updated: May 9, 2019

Bearded irises are tall perennial plants that produce large, amazing and colorful flowers with pointy foliage. Depending on the variety, they can grow 6 inches to 4 feet tall. Sunlight is essential for irises and moist, well-drained soil.

Need container or pot at least 12 inches in diameter with drainage holes in the bottom. Place container in area that will receive 6 to 8 hours of direct sunlight each day.

Water when soil feels dry about 2 inches deep. Water deeply but infrequently.

If you notice aphids or other bugs, spray with insecticidal soap once a week.

Cut the flower stalks down to the base of the plant once they are finished blooming and discard cuttings.

Divide the irises every year at the end of summer or whenever container becomes too crowded. When you dig up rhizomes, knock off loose dirt, separate and discard any old rhizomes that do not have white roots. Replant the separated rhizomes in a larger container or they can be placed in several small containers.
