  • scissorsPruning

    Pruning the Tall Bearded Iris involves cutting back the flower stalks to the base after blooming to encourage healthy growth and prevent seed development. Remove any damaged or diseased leaves at this time. In late summer or early fall, trim foliage to a height of about 4 to 6 inches to prepare for winter and promote air circulation.

  • circleLife cycle

    The Iris 'Norfolk Belle' (Tall Bearded Iris) begins its life as a rhizome, which is a type of underground stem capable of producing the roots and shoots necessary for growth. Upon breaking dormancy in early spring, new shoots emerge from the rhizome, leading to the development of long, sword-shaped leaves and a flowering stalk. The plant blooms in late spring to early summer, displaying its distinctive flowers that attract pollinators for sexual reproduction. After flowering, seed pods may form, although many gardeners remove these to encourage more vigorous plant growth. Throughout the summer, the foliage continues to photosynthesize, providing energy for the rhizome to store. As autumn approaches, the foliage begins to die back, and the plant enters a period of dormancy during the winter months, conserving energy within the rhizome for the next growing cycle.

    • Propogation time

      Late Summer to Early Fall

    • Propogation: The most popular method for propagating the Iris 'Norfolk Belle', also known as the Tall Bearded Iris, is through division. This is best done in late summer, after the blooming period when the rhizomes have new growth. To propagate through division, dig up the iris clump carefully to avoid damage to the rhizomes. Clean the soil off the rhizomes and inspect them for signs of disease or damage; discard any that are not healthy. Using a sharp knife, cut the rhizomes apart, ensuring that each division has at least one healthy fan of leaves and a portion of the root system. Shorten the leaves to about one third of their original length, which is approximately 4 to 6 inches (10 to 15 centimeters), to reduce water loss while the newly planted division establishes. Replant the divisions at least 12 to 24 inches apart (30 to 60 centimeters), placing the rhizome just at or slightly below the surface of the soil, and water well to settle the soil around them.
