The Q&A Archives: Iris Care

Question: What should I do with iris bulbs after the iris are done blooming?

Answer: If you're growing Dutch Iris, or Reticulata Iris, wait until the foliage is fully mature and has shriveled and died. Then dig the bulbs and store them in a cool, dry place for about two months. After the resting period, replant them 4" inches deep and 3" to 4" inches apart in rich, well-draining soil. Or, you can just leave the bulbs in the ground to bloom again next spring. Dig and divide every 3-4 years if they become overcrowded and bloom is poor.
