Thanks all who asked questions, trying to give best answer as I can :-).
Where are you located?
[A: Just north of Toronto, I consider it zone 4]
When was the rose planted?
[A: I bought it 2 years ago at season end, maybe in Sep, so I guess it was not in its best shape when I bought it, but it seems vigorous now]
Was it a budded plant, or is it on its own roots?
[A: Not sure I understand this question. It was sold in a container, so the answer is it's on its own roots?]
What has your weather been like?
[Being in Toronto, summer is on cool side,. But this year has been warmer, though. Quite a number of ~30C days. This Sep was nice too, 20+C average in day time]
what are the conditions where you've planted it...sun, shade, near trees?
[A: It's planted along my side wall. Decent amount of sun, 8+ hours /day in peak summer, but could be substantially shorter in fall when sun sets earlier. I'd say 6hours give or take]
And have you pruned it?
[A: yes, once. I think last year before winter (or alreay in winter, can't remember the exact time, but it was quite cold when I pruned). I left almost only the main stem (it had one and only primary stem to begin with, tied to lattice in "S" shape).
