> what ARE the signs of breaking dormancy?
Let's start with the signs of domancy....
Fully dormant rhizomes have no leaves left. =
Even the growing point looks pretty well
callused over. Arils may have some dried
up roots, but a lot of arilbreds drop their
roots entirely. You can end up with something
that looks more like a bulb than a rhizome.
You can catch the earliest signs of breaking
dormancy on ones stored in paper bags
because there's no soil to hide the growing
points. First, a white tip breaks through the
callused skin then new leaves break forth.
On established clumps, just watch for the
new leaves to break ground.

Arilbred rhizomes are "supposed" to be
smaller than TB rhizomes because they
don't store as much water. But in my =
climate some of them outgrow the TBs.
If there's any foliage, I'd deem the rhizome
only partially dormant.

Sounds like what we usually call
green dormancy. =

It's pretty safe to judge the rhizomes
of quarterbreds by TB standards, and
most of today's halfbreds go only
partially dormant. It's when you get =
into the predominantly aril ones that
you need to be aware of the amount
and type of aril content -- and whether
you need to make allowances for
