How to Take Care of a Siberian Iris Flower
The Siberian iris features a typical drooping iris bloom. Flower colors include deep red, purple, yellow and white. The foliage is more grass-like and upright than that of bearded irises and other well-known garden iris varieties. The blossoms flower in spring and early summer and the foliage persists until late summer. Siberian irises tolerate both moist and dry soils, and have the ability to grow well in most beds and climate conditions. These relatively care-free plants survive and flower dependably for years.

Water the irises approximately once weekly during the first summer after planting. Supply enough water at each irrigation to maintain the moisture in the top 6 inches of soil. Established, two year or older plants only require irrigation during dry periods.
-
2
Mulch over the iris bed with a 2-inch layer of wood chips or a similar organic mulch. Leave the crown of the plants uncovered when mulching. Replenish the wood chips each year in spring.

Fertilize the Siberian irises in spring when the first leaves push up. Apply an all-purpose, balanced fertilizer at the package rate recommendation.

4
Cut back the flower stalks to their base after all the flower buds along the stalk have completed blooming. Use sharp shears and make a clean cut to prevent damage to the plant.

5
Prune off the old foliage in fall when it yellows and dies back naturally. Cut the foliage off at the base of the plant and dispose of it.

Tips & Warnings
Siberian irises typically don't begin blooming well until their second year after planting.
Digging up and dividing the rhizomes isn't necessary for Siberian iris varieties, but you can divide every three to five years if you want more plants.
