Prepare the planting site and place the selected rhizomes in the ground.

1. Dig holes about four inches deep and create a small mound in the center.
2. Position the rhizomes on top of the mound with roots draping down the sides.
3. Ensure that the rhizomes are slightly exposed to avoid rot.
4. Plant in groups of three to seven, with leaves facing the same direction.

After planting, water the rhizomes thoroughly.

1. This helps establish the plants and encourages healthy growth.
2. With proper care, you can expect beautiful iris flowers in the spring.
