Re: pruning techniques for new roses

Hi guys,
   I'm new to the list, so please forgive me if this has already been
thoroughly discussed!  Last year I lost over 30 roses to a rose fungus in
the canker family.  The symptoms were canes that turned black all the way
down to the crown.  There was basically no cure except to continually weed
out diseased canes/plants and keep on a regularly scheduled spray routine.
Others in my area (zone 10), experienced the same thing to a lesser degree,
and have attributed some of the problem to the enormous rains of El Nino.
It was extremely contagious.
   However, I have received many bareroot plants that had black canes only
on the tips.  This is not a problem.
