Iris lovers who enjoy a variety of irises in their gardens are choosing Siberian Irises in increasing numbers. Siberian irises provide tall landscape plants with blooms in purple, blue, pink, yellow and white. Siberian irises adapt more readily to a variety of soil conditions than some other iris varieties and avoid some of the common iris problems. Cut back a Siberian iris carefully to ensure the continued health of the plant.
Deadhead the Siberian iris plant by removing the faded blossoms when they wilt on the plants. Use the pruning shears to remove the blossoms at the point where they connect with the stems. While deadheading is not mandatory, it will make the irises more attractive.
Clip off all of the bloom stalks from just above the crowns of the plant when the plant finishes blossoming for the season. Leave the other foliage intact at this time.
Remove the remaining foliage from the Siberian iris in the autumn. When the foliage withers and browns, cut off all growth 1 inch above the soil level. Discard the foliage.
