I would wait until I see a cane grow up with different foliage that alerts you to the fact it comes from rootstock and then dig down and tear that cane off. Own root can be easier. You will recognize different rootstocks over time.

My take, Sheila, ^^ on a1an’s question is that he doesn’t know if this is a new cane ( of the desired rose) arising from the bud union, or if the new growth is arising from the basal region of a pre-existing cane. He could tell now by excavating mulch and soil, but he’s not going to do so till early next year. He would like to see for himself that what we are all told happens ( brand new canes really can grow from the bud union) really does happen, as we here bury the bud union. It’s like Scooter Libby threw sand in our eyes. Of course the new growth he sees may be coming from a pre-existing cane. He wants us to predict, now, which it is.

I'm so busy digging for weed buried emitters, I would probably skip that step of digging at the new basals but I see what you mean, rifis.

Indeed rifis has summed up what I seek. Don't plan to do the disturbance now...too many leaves cans, and possibly Black Spot Leaf Debris on the base . Don't really want to also chance buying some BS leaf spores. Rater have a -clean- working area to contend with if I'm going to disturb the area.

What I still haven't gotten clarity , on BR grafted roses, where there is 3-5 primary stems coming off of it, was it from 3-5 budded points, and or was it just a single bud point....never did seem to find a agreeable consensus on that.

I recommend you call or email Rachel at Palatine and ask her. So she can tell you what she told me. When I told her I assumed each cane on a new BR was individually budded ( as it certainly looks that way), she laughed and said no grower could afford to do that. Plus, it’s not necessary. She described what happens as “ magic”.

Yes, that is correct! It's just ONE scion on one graft point, UNLESS there are two different roses grafted onto the same rootstock which I have seen these past couple of years.

Makes sense, one of the points of grafting roses is the ability to produce more, faster. It would kind of take a lot of extra time and effort if you had to do multiple canes on every rose.
