After the plant is fully established (2-3 years), dig up the plant, ensuring you capture all the roots.
Remove the bulbs and soil around them.
Replant in a full sun to part sun spot in rich soil with good drainage or a container plant mix.
Dig the hole twice as wide and the same depth as the original or three times the height of the bulb deep.
Add root hormone at the bottom of the hole, place the bulbs in the center, and water.
Add compost and supplemental garden soil mixed with the native soil to the hole.
Water around the plant again and keep the soil moist but not soggy in well-draining soil. Mulch around the roots to retain moisture.
