My wife and I planted a variety of climbers called Angel face three years ago. The vines have grown just fantastic, but have yet to see a single flower. Late last fall we did see one bud, but it never opened before the onset of winter. Am I being inpatient or could I have some type of other problem? I have been told to have soil tested and am in the process of doing so. Does anyone know the proper PH for roses? Thanks in advance for any help....
