Can I bud a scion , or chip bud, upon a wild rose sucker?
I have two possibilities for budding, I think:
two small (8" tall and 11" tall 'Gloire des Rosomanes' that bloomed for the first time July 2014, are they too old to bud 'Sutters Gold' upon them?
I also have several suckers of Rosa californica, that are several inches tall, have not yet flowered and are about the thickness of a #2 pencil, would it be possible to bud roses upon them? I'm thinking of budding 'Westside Road Cream Tea'.
