Do you have any special secret or routine you use in handling rhizomes as you plant them? If they seem a little dry do you soak the roots? How often do you water? I know weather will effect watering. Do you use any rooting compound in a liquid such as "Thrive" One thing I do is cover each newly planted rhizome with a milk basket to provide some partial shade until they are established. I usually leave them on about a month. Tell us your routine. Here is an uninspiring picture of some milk baskets, each with a newly planted rhizome from a recently received order under it.
