Default [IBC] brown edges on azalea flowers.....why?

-----Original Message-----
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 c
hange environmental conditions (you can use fungicides, but they don't give good coverage on quickly-opening parts like buds and flowers.
