I hate to tell you, Janet, but that has not been my experience so far.
It depends on the source of rot, though. If the original rz rotted due
to borer or deer injury, and if such injury can be avoided in the
increases, then the plant still has potential for future survival and
growth. If, however, the rot was precipitated by "standard" climatic
factors alone, I have found the rotters will continue to do so each year
until the clump disappears entirely. Of course if there are atypical
climatic conditions such as those my area experienced this spring, it's
possible to lose large numbers of plants to rot that wouldn't have
expired under more "standard" weather conditions here. About 30 of the
TBs that rotted and died this year have been replaced under Cooley's
"Nightmare Insurance" plan, so we'll see how they do IF we get more
typical weather patterns over the next 12 months.
Stay tuned ...
Laurie
