watering
Siberian iris (Iris 'Quiet Shape') should be watered deeply and thoroughly. Water once a week during the growing season, allowing the top 2-3 inches of soil to dry out between waterings. During extremely hot weather, it may require more frequent watering. Reduce watering in late summer and autumn, allowing the soil to become mostly dry before the next watering. During colder months, it is best not to water the Siberian iris at all, as they are adapted to dry conditions during winter.
sunlight
Siberian iris (Iris 'Quiet Shape') will thrive in full sun or partial shade with at least 4-6 hours of direct sunlight each day. Locations with partial afternoon shade are often the best for this plant species. Too much sun can scorch the foliage while too much shade can lead to poor flowering. Optimally, Siberian iris should get morning sun and filtered afternoon light.
pruning
The Siberian iris (Iris 'Quiet Shape') should be pruned annually in the late winter or early spring, before new growth begins. To ensure proper nutrition, prune only the dead, damaged, or diseased foliage, stems, and flowers. For a robust, full plant, remove no more than 1-third of the stems every year. If you prune off more than this, you may be left with an unbalanced plant. Make sure to use sharp pruners and trim the stems just above the crown where the stem attaches to the bulb.
