DND-I sort of follow Arlyn's "rules" by some experimentation. No bleach soak; plant right away if newly out of the ground, otherwise a short stint of drinking some moisture. Usually I just rinse off if needed and then plant, rhizome visible, tamping down soil around the roots and water in. John suggested using a weak solution of monopotassium phosphate [fertilizer without any nitrogen] solution for the soak and first 2 waterings. This may help the plants get a good start, so am trying that.
