Answer: Sounds as though the time is ripe to renovate your iris bed! Iris grow from rhizomes that appreciate well-draining soil that 's been amended with organic matter. Dig the rhizomes, cut the foliage and the roots to about six-inches, divide the rhizomes by cutting off the ends (with the foliage attached) and discarding the old, leafless center portions. Then spread 3-4 inches of compost or other organic matter over the planting area and dig it in. Replant the rhizomes so the tops are just slightly below the soil surface. Roots should deeply penetrate the newly amended soil and hold the plants upright. Water well until fall rains take over. In the spring your iris should sprout new leaves, and glorious flowers.
