Follow these easy steps:
1. Dig up the entire clump of rhizomes with a garden fork or split off individual rhizomes. Try to avoid damaging the roots or the leaves (see photo 1).
2. Shake excess dirt off and remove dead material from the clump. Remove enough so that the clump is fully exposed.
3. Trim the roots to about 2” long (see photo 3).
4. Trim the leaves down to 4-6”. Trim in at an angle on each side (see photo 4).
5. Replant rhizomes so that the top of the rhizome is visible and flush with the soil (see photo 5).
If necessary amend the soil of the planting location with bone meal or compost. So long as the soil is light your iris should do fine.
Pack soil firmly and water moderately.
