Here are some photos. Thank you.

If your winds are so strong they're snapping canes off from the base even without the weight of leaves and flowers, you should bury your roses more deeply. I once had a rose do the same, snap off right at the graft on the last remaining cane I had. Killed the rose, of course. I wish I have buried it deeper to protect it from our strong winds. I don't know anything about crown gall though, hopefully someone with more trained eyes can help with that.

MM: “Killed the rose, of course”

@a1an take note. What say thee?

Its not crown gall, that's just the bud union, which typically manifests as a large "knot" where the two roses graft together.

Thanks everyone, this is a relief to hear

When a cane snaps off like that I always figure that that particular cane was probably weak and unhealthy and that the plant wanted to lose it... Maybe coddle that plant a bit next season, to strengthen it (the entire plant is what I mean) somewhat?

Noted Rifis. I was thinking about the one 2 stems that are new that are about 8" away from the main graft. I was thinking/suspect it has self rooted and may be growing on -own root- ?

re: the cane snapping, I can't see that happening unless it was leaf/bloom top heavy loaded. For it to just do that bare, survival of the fittest - stem was a goner already ?

"stem was a goner already ?" That's what I think,a1an.
