Question
I live in a zone 5 climate. Will the ragosa rose survive here? Are there any pest problems associated with this plant? Is full sun ok?

Thanks

Answer
 It really should be ok in your zone.  This year there has been so much rain and moisture that fungus has hit a lot of the roses.  If you are getting yellow leaves, spray with a fungicide about every 10 days until it's gone.  Also take off those leaves.  Ragosa roses are pretty hardy though.
