  • water dropWater

    Tall Bearded Irises like 'Reg Wall' should be watered deeply and infrequently to encourage deep root growth, with the frequency depending on the climate and soil conditions. On average, watering every 7 to 10 days during the growing season is adequate. They require about one inch of water per week, including rainfall. In arid climates or during particularly hot, dry periods, increase watering slightly. Be sure to water at the base of the plant to avoid wetting the foliage, as this can encourage disease. When rainfall is sufficient, supplemental watering may not be necessary. Always allow the soil to dry out slightly between waterings.

  • sunLight

    Tall Bearded Iris, such as 'Reg Wall,' thrives in full sun conditions where they can receive at least six hours of direct sunlight each day. An ideal spot would be in an area that is exposed to the morning sun and has some protection from the intense afternoon sun, although they are quite adaptable to full day sun as long as they are well-watered. Avoid planting in locations that are overly shaded, as this can affect flowering.

  • thermometerTemperature

    Tall Bearded Iris 'Reg Wall' can tolerate a wide range of temperatures, but they grow best in regions with a distinct cold period during the winter, as the cold helps promote blooming. They can survive winter temperatures down to about -20°F and summer temperatures well over 90°F. The ideal temperature range for their growth is between 55°F and 75°F.

  • scissorsPruning

    Prune Tall Bearded Irises like 'Reg Wall' to remove spent flower stalks after blooming and cut back the foliage to about 6 inches in late fall to minimize overwintering pests and diseases. Pruning encourages better air circulation and focuses the plant's energy on root and rhizome development. The best time for pruning is immediately after the flowers have faded, and a more thorough pruning should be carried out once the growing season has ended, typically in late autumn.

    As needed

  • bambooSoil

    The Tall Bearded Iris, such as 'Reg Wall,' thrives in well-drained soil with a slightly acidic to neutral pH of 6.8 to 7.0. The best soil mix is a combination of loamy garden soil, compost, and sharp sand to improve drainage. It's important to avoid heavy clay soils and to ensure good air circulation around the rhizomes to prevent rot.

  • plantRepotting

    Tall Bearded Irises like 'Reg Wall' do not require frequent repotting and should be divided and repotted every 3 to 5 years. It's essential to replant the rhizomes at the soil surface with roots spread outwards and downwards.

  • water dropsHumidity & Misting

    Tall Bearded Irises, including 'Reg Wall,' tolerate a wide range of humidity levels but prefer lower humidity environments. It's best to ensure they have good air circulation to prevent issues like rhizome rot.

  • circleLife cycle

    The life cycle of Iris 'Reg Wall', also known as Tall Bearded Iris, begins with seed germination, which occurs in a damp, well-drained growing medium. After germination, the seedling grows into a young plant with sword-shaped leaves and forms an underground storage organ known as a rhizome. Over time, the rhizome develops and stores nutrients which enable the iris to endure periods of dormancy and regrow in subsequent seasons. Once mature, the iris produces distinctive, colorful flowers typically in late spring to early summer, which may be pollinated by insects to produce seeds. After the flowering period, the plant enters a phase of senescence for the rest of the growing season, where foliage may die back as the plant prepares for dormancy. The dormant rhizome can survive through cold winter months before resuming growth in the next cycle, with the capacity to multiply and produce new shoots that will become separate but genetically identical plants.

      Late Summer

    • The Iris 'Reg Wall', which belongs to the tall bearded (TB) group, is most commonly propagated through division of its rhizomes. This process is ideally performed after the flowering period, when the plants are dormant, typically late summer to early fall. Gardeners should lift the clump of iris carefully to minimize damage to the roots and rhizomes. Using a sharp, clean knife, the clump is then divided by cutting the rhizomes into pieces, ensuring that each division has one or more fan-shaped growths of leaves and a portion of the rhizome. The cuts should be made a few inches away from the leaf fans. These divisions are then replanted in well-draining soil, with the rhizome slightly exposed above the soil level. The newly planted divisions should be watered in gently to help establish them in their new location.
