watering

Iris 'Katharine Hodgkin' should be watered deeply and regularly during the growing season (from late spring to summer) to ensure it thrives. Depending on the climate and soil condition, water once or twice a week. Make sure to water until the top 2 to 3 inches of soil are moist, and don’t let the soil dry out. Once the leaves become golden brown and wilted, this is a sign of overwatering or under-watering, so adjust accordingly. In areas with hotter climates, water 2 to 3 times a week, giving it enough water to reach a depth of 6 to 8 inches. In the cooler climates, 1 deep watering per week is usually sufficient. During the winter months, water sparingly. Allow the soil to dry fully between waterings.

sunlight

Iris 'Katharine Hodgkin' plants require full sun in order to thrive. The best time to give them sunlight is during the brightest hours of the day, usually between 10am and 4pm. During these hours, the plant should receive at least 6 hours of direct sunlight, ideally 8 or more hours for maximum growth. Depending on the location and the season, it may be beneficial to provide the plants with light into the later hours of the day to ensure they are getting the full sun required for optimal growth.

pruning

Iris 'Katharine Hodgkin' should be pruned in late winter to early spring, before active growth begins. Prune off any dead, diseased, or broken stems at the base of the plant. Cut back the foliage to a height of 8-10 inches, leaving 2 or 3 healthy buds visible on the remaining stem. The blooms of the 'Katharine Hodgkin' iris tend to be short-lived, so it is best to remove faded, damaged, or misshaped blooms as soon as possible during the blooming season.
