#ProPlantTips for Care:

Plant Dutch Iris bulbs about 4 inches apart and 4 inches deep in a well-drained, full sun location. In hotter climates, you can plant your bulbs in partial sun areas. Provide moderate moisture all growing season, but reduce watering once the foliage yellows. Soggy locations should be avoided as the bulbs can rot. Deadhead after flowers fade but keep the leaves to make food for the bulbs. Every few years it is recommended to divide the bulbs and clean out any older, non-productive roots to maintain vigor. Prune away the foliage after it yellows to the ground.
