Siberian iris

Water Siberian iris (Iris 'Eric the Red') plants at least once per week in order to keep the soil moist. During its growing period, which is typically late spring and early summer, water the plants deeply and allow them to dry out slightly between waterings. Once established, the plants don't need to be watered as often. During the hot summer months, increase the frequency of watering to once or twice per week. However, during the cooler months of fall and winter, reduce the frequency of watering to once every 2 weeks. Make sure the soil at the base of the plant has good drainage and water slowly to ensure proper absorption.

Siberian iris (Iris 'Eric the Red') thrives in a sunny or partially shaded location that receives at least 6 hours of full sun daily. During the peak bloom season from late spring to mid-summer, it may require up to 8 hours of sun for best flowering. In summer, the bright sun rays may be too intense and result in leaf burn, so a few hours of afternoon shade during this season is generally beneficial.

Siberian iris (Iris 'Eric the Red') should be pruned in early spring, or late winter in warmer zones, removing any dead or damaged foliage before the new emerging growth appears. Pruning can help with improved blooming and vigor of the plant, as well as helping to keep it to size and appearance. To prune, snip off any dead or damaged foliage at the base of the plant, and then prune back foliage to within 2 - 3 inches of the base. This will help to promote denser, more productive growth and prolonged blooming. Rejuvenation pruning may also be beneficial, in which older, clumpy iris plants can be cut back to the ground in late winter or early spring to promote vigorous, youthful growth.
