  • water dropWater

    Katharine Hodgkin Iris, commonly known as the Reticulata Iris, should be watered moderately. During the growing season, keep the soil consistently moist but never waterlogged. Water the plant thoroughly once a week, providing about one gallon of water per session for a regular-sized garden plant. It's crucial to reduce watering after the blooming period as the plant enters dormancy; during this time, watering every 2-3 weeks is sufficient. Ensure that the soil has good drainage to prevent root rot.

  • sunLight

    The Katharine Hodgkin Iris thrives best in full sunlight to partial shade. It should be placed in a spot that receives at least six hours of direct sunlight per day. However, in regions with very intense sun, some afternoon shade is beneficial to prevent scorching of the leaves. This iris can also tolerate light dappled shade, particularly in hotter climates.

  • thermometerTemperature

    The Katharine Hodgkin Iris prefers temperate conditions and is hardy in zones 5 through 9. It can survive winter temperatures down to 5°F and is comfortable during the growing season in temperatures ranging between 60°F and 75°F. However, it should be protected from extreme heat, as temperatures consistently above 90°F may adversely affect the plant.

  • scissorsPruning

    Pruning the Katharine Hodgkin Iris is mainly for aesthetic purposes and to remove spent blooms. After flowering, cut back the flower stalk to the base of the plant to encourage tidy growth. In late summer or fall, when leaves yellow, trim the foliage down to ground level. Pruning is usually done annually to prevent diseases and pests and to maintain plant health.

  • circleLife cycle

    Iris 'Katharine Hodgkin' begins its life cycle as a bulb, which is typically planted in the fall, lying dormant in the soil through winter until the proper conditions for growth are met. In late winter to early spring, the plant breaks dormancy, sending up leaves and a flower stalk, with the unique pale blue to yellow flowers blooming from late winter to early spring. After flowering, the foliage continues to photosynthesize and store energy in the bulb for the next season. Once the leaves die back in late spring or early summer, the plant enters a period of dormancy during the warmer months. The bulbs may divide, creating offsets that can be separated and replanted to propagate the plant. Each year, the cycle repeats with the bulb re-sprouting in the following season, carrying on the succession of growth, flowering, and dormancy.

      Late Summer

    • The most popular method of propagation for the Iris 'Katharine Hodgkin', commonly known as the Dwarf Iris, is by dividing its bulbs. This process is ideally done in late summer, after the foliage has died back, and the bulbs have entered a dormant period. To propagate, gently lift the clumps of bulbs from the ground using a spade or fork and carefully separate the offsets from the parent bulb. These offsets are miniature bulbs that form at the base of the parent bulb. Replant the offsets at a depth of approximately 3 to 4 inches (7.5 to 10 centimeters) and space them about 3 inches (7.5 centimeters) apart in well-draining, fertile soil with plenty of sunlight. Ensure that the pointy end of the bulb is facing upwards. Water thoroughly after planting to establish the bulbs in their new location.
