I'd appreciate some help on this one. We've got some shrub roses that
we've waited too long to prune here in Nevada. We should have pruned
them by May 1 AND we are having a warmer than normal spring (now in
the 80's) where normally it is 60's for this time of year. Many of
the roses already have a first flush of almost mature buds.
I am concerned that if we prune them too hard (shearing all the buds
and cutting the canes in half or more) that after putting so much
energy into this first flush, that they will be disadvantaged/slow to
recover and create a second bloom.
What do you think?
