RE: when to divide PCI
Rodney responded ...
>If you want to divide them do it in the Fall - October - when
new root growth, if the divisions do not show new white roots then soak
them continuously in a bucket until roots show before replanting.
Is there something in particular you look for to know they are ready to
How long can you keep them in water?
When to divide - usually one wants do this in the early Fall, here it is
done in LATE September at the Earliest, usually in October is safe. If
plants do not show new white roots when dug then go the soaking route,
NEVER let them dry out and water new plantings regularly. The rhizomes
should be in the water, but not the entire plant, and can be left this
way for a long time. One member of our club left his in a tub until
SPRING and had bloom! This is not recommended because of the danger of
later rot due to water molds etc.
