Dividing Irises

Beardless (Japanese or Siberian) irises need to be divided regularly. As they grow, the center of the plant weakens or dies. Dig out the clump, cut out 4-to 6-inch segments from the outer ring and discard the center. Plant your renewed irises in soil that has been improved with compost or other organic matter, making certain to keep them at the same depth as they were before.
