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?

p.s.. This is my first post here!

Which roses did you buy, and where did you buy them from, and in what
condition were they when you bought them? What was your soil
preparation
and how is it's drainange and pH? What have you sprayed them with and how
often have you watered with how much? What has your fertilization program
been? Did you check for vole damage to the roots?

A lot more information is needed to even have a preliminary diagnosis.


Thank you for taking the time to reply.
