I live in Northern California though I do not know the zone I am
currently living in and I have a question regarding pruning. I just
recently moved to the mountains I live at the 3000 foot level so I am
not really in the snow country though we do get little bit of snow.
When I lived in the San Joaquin Valley I always trimmed my rose bush in
January or around that time. My Mother-in-law, who lives next door,
has told me not to trim my rose bush until after the frost season ends
which according to her is around April. I am concerned isn't that
too late? My beloved rose bush is already sprouting; in fact I am
shocked at how much new growth she has. What do you recommend? Should
I wait until April to prune her back? I would appreciate any and all
advice on this subject.

Thanks,
Marianne
