Growing a Bearded Iris

Updated on March 12, 2011

 There are many varieties of irises such as Siberian and Bearded irises. Bearded are the most popular especially in the south and grow quite well zones 3 to 9. They are easy to grow and are drought tolerant but they grow best in damp soil. They bloom in the spring and can last through the summer and maybe even early fall with plenty of water and fertilizer.


 The location of your bearded irises is key to their growth and well being. They need full sun to partial shade. Their pretty colors of lavender, yellow and white, will brighten up a garden or add curb appeal to a sidewalk or driveway.

Planting the Iris

Once you have picked a location, plant your bearded iris rhizomes in late summer or early fall somewhat below the surface of the soil. Or if the iris is in a container, plant in early spring. Provide good drainage so the roots will stay moist, which will encourage continued growth. Make sure the soil has organic matter.

Dividing Bearded Irises

After two to three years, you can dig and divide the iris in the fall. Cut away any damage part of the rhizome and replant making sure each piece you divided has healthy roots and leaves so it will re bloom.

Promoting Continued Growth

Once your bearded iris is planted, feed in the with a slow-released fertilizer. Follow the directions on the manufacturer's label. Water frequently once planted for the first few weeks. During the summer bearded, irises will need plenty of water.

      Do irises need bone meal?

      I've always enjoyed having iris's growing in my flower gardens. Separating them can be a little work, but so worth it. I'll try your suggestion to use a slow-release fertilizer for longer lasting blooms. Voted Up and useful!
