How do I replant Iris?
You likely have bearded iris (Iris germanica), which need full sun and good drainage. The rhizome (the horizontal stem that the foliage grows from) need to be visible at the soil surface. Planting them deeper encourages rot and disease. Iris are best divided and moved in mid- to late summer, but you can move them earlier in the year if you must.
