hi Yet another new question. I have 2 dawn redwoods, and have been working
on them for 2-3 years with good success. Last fall, I wired one of them
completely. Both set in my garage from frost (mid September in Vermont) till
about November when they went into a cold greenhouse. The garage certainly
dipped below freezing.
THe one that was wired, has off color(not brown) leaves, and no new growth.
The other is vibrantly green, and already has new growth. I was wondering if
anyone had ideas of what might have happened(frost???0 and what I might do.
It is a great gnarly trunk, and I want ot do what I need to do.
Thanks Rodger Kessler(zone3/4)

I'm with Nina here, sounds like water. But . . .
I assume this is a bonsai, and isn't a "-Second- flowering event" asking a
lot from this tree? Even if you are super feeding it, that has to be a
drain on it's strength.
That said (asked), understand that _I_ don't have any azalea's in pots.

But, when they open (before they are fully open) the edges of the
flowers are turning brown and ruining the image. or, the may have
rotted because the flowers buds as they were breaking
collected too much moisture and rotted (we've had a lot of rain
recently)

As a plant pathologist, I'd opt for your second guess. If you had a lot
of rain and your tree is in a spot where it doesn't get good air
circulation, it is susceptible to Botrytis flower blight. Botrytis is
ubiquitous, so the only way to avoid it is to change environmental
conditions (you can use fungicides, but they don't give good coverage on
quickly-opening parts like buds and flowers.
