Siberian iris

The Siberian iris (Iris 'Baby Sister') should be watered deeply every 5 days. During summer months, when temperatures are warmer, it is best to water twice a week. Water should be at the base of the plant and should penetrate the soil 6 inches deep. During dry periods, it’s helpful to check the soil 2 inches down to ensure that the soil is still moist. During the winter, a deep watering is generally only needed once a month.

Siberian iris (Iris 'Baby Sister') prefers full sun for at least 6 to 8 hours per day in order to best thrive and produce abundant blooms. Morning sun is especially beneficial but the plant will also tolerate some afternoon shade. To ensure success with this plant, it is important to provide it with plenty of direct sunlight for at least 6 to 8 hours a day and at least 5 hours of direct sun a day while the plants are actively growing and blooming.

Siberian iris (Iris 'Baby Sister') should be pruned in early spring, when the soil warms and the shoots have grown approximately 2 to 3 inches in length. Cut off all the winter damaged foliage and prune the top 1 or 2 inches of each stem. This will encourage bushier growth and produce more colorful flowers. Once the flowers have wilted, the spent blossoms should be removed to discourage reseeding. Additionally, some of the oldest leaf clumps may be trimmed back to the ground to encourage new shoots.
