Pre-treatment: Wild harvested tubers are planted whole, but are subdivided into 1-2 tubers segments by cutting the cordlike root attaching the tubers to each other. Tuber segments are then placed in nursery trade quart sized pots that have been filled three-fourths full with a commercial potting soil. Tuber segments are placed in the filled pots on top of the potting mix and then covered with additional potting soil. Filled pots are gently hand compacted to ensure good tuber soil contact. Properly filled pots should have at least one inch of potting soil covering the tubers.

Establishment: Tubers are typically collected from wild populations during late dormancy (February-March). Care should be taken to avoid overharvesting of tubers from wild populations.
