dwarf crested iris

Dwarf crested iris (Iris cristata 'Alba') should be watered every 5 to 7 days during the warmer months and every 10 to 14 days during the cooler months. Water deeply to ensure thorough irrigation. Make sure the top several inches of soil are moist, but not saturated. Allow the soil to dry out slightly between watering. Excess water can lead to root rot and can kill the plant.

Dwarf crested iris (Iris cristata 'Alba') does best with full sunlight for at least 4 to 6 hours each day. Sunlight helps bring out the bright white blooms of the iris in spring. The flowers of this plant are more likely to be droopy and severely weakened if given too little sun. If possible, find a spot for the iris where it can receive full sunlight for most of the day. If that isn't feasible, try for several hours of afternoon sun. Dwarf crested iris should not be placed in an overly shaded spot as this will diminish the flowers that appear in spring.

Dwarf Crested Iris (Iris cristata 'Alba') should be pruned twice a year, once in the spring and once in the fall. In the spring, cut the foliage back about 1-third of its length. Additionally, remove any foliage that may have been damaged by winter cold or hail. In the fall, trim the foliage back to the ground, or just a few inches above the soil. This will encourage new growth in the spring. Pruning will help to keep the plant healthy and encourage new blooms each season.
