Barry Blyth recommends that you soak them for a "short" time if they look too dried out before planting when they are shipped from Australia. I ususally don't, but I have had some that sat around a while before planting, and I soaked them for about 30 minutes before I planted them. I think it would be best to not soak them too long, but rather water them every day unless it rains for the first week or until you see growth starting. Are the leaves nice and green, or are they dry and brown? The roots that are on the plant most likely will die, and new ones will come from the rhizome anyway.
