watering
Siberian iris (Iris 'Butter and Sugar') should be watered deeply to encourage strong root growth. They should receive at least 1" of water per week from rain or irrigation. During hot, dry months, these plants may require additional water. Irrigate deeply, allowing the soil to become moist, but not wet. Allow the soil to dry out slightly between watering. Applying a layer of mulch around the plants can help to conserve water and reduce weeds.
sunlight
Siberian iris (Iris 'Butter and Sugar') plants grow and flower best in full sun, with at least 6 hours of direct sunlight every day. In areas with strong sun and heat, they should be provided with some shade in the afternoon. They are quite adaptable and can tolerate light shade, but will produce fewer blooms. With adequate sunshine and moisture, Siberian iris plants will bloom in the early summer. Once they have finished flowering, they require less light and can even tolerate partial shade.
pruning
Siberian iris (Iris 'Butter and Sugar') should be pruned in early spring, when new growth just begins to appear. Pruning should be minimal, as these plants don't need excessive pruning to maintain their shape and size. Some of the old, flowering stems should be trimmed off at the base to allow new growth to emerge. Deadheading of spent blooms is also recommended to keep the plants blooming throughout the season. In late summer, old foliage should be trimmed off, and the plant can be pruned back by 1-third of its original height. Don't prune off any new growth, however, as it will also remove the next year's flower buds.
