Canes blacken and die
 

Planted 2 Hybrid Teas and a climber this spring. The HT grew into canes,
flowered once and then wilted to death. The leaves wilted first, slowly, as
though they were not getting water. The canes then turned black. I read
the Post by Josephine about the wilting buds and the Rose Midge. According
to sources on the internet, the Midge causes leaf damage, not damage to the
canes.


What would cause the un-damaged canes to blacken back to the bud union and
die? Rose canker might be likely but I have no experience with it:

the climber had the same thing on several canes but has survived. BTW I
have Black Walnut trees on my lot and they are known to be harmful to many
ornamentals, but Rose is not one of the species mentioned.

Any comments?
