I have a very old hedge of unidentified roses.
The canes grow at least 8 to
10 feet long and bear lots of very small single
white flowers. It has really
viscious thorns. It hasn't been pruned of
thinned for many years. Today, I
found brown irregular growths on most of the
heaviest stems. All the canes
with the growths are dead, but the rest of the
plants appear to be very
strong and healthy. Can't tell from the internet
searches or my books
whether this a gall or canker. The growths are
from two to six inches long
and double the thickness of the stems. I intend
to cut the entire hedge down
and burn the canes as I do not want this to
spread to the dozen plus roses I
bought last year (mostly rugosa and the
Canadian Explorer series). Am I
being too drastic? Any suggestions?
