If highs stay in the 50s, you will get new growth after pruning, and then if lows of 25 occur, the new growth will be killed. I would wait until lows of 25 or 26 are unlikely, but I don't know when that is in your area. Mid-February?

MIC-Well its a crap shoot. We can get a late frost(low 29-32) as late as the end of March and the days could be in the mid to high 60's or it could be??? Its really hard to tell here. What temp would it have to be for the new growth to get fried (25 or more like 32)?
One year we never had a spring, just started HOT in April and continued. So I guess it is a guessing game. What about the oil spray? Thanks for the help

30 or 32 F has no effect on roses. 28 F is probably safe.

You can do the oil spray at any time in the winter, or skip it, if you wish. Not every grower does that.

I usually spray the oil on the roses after prunning because I do it the same time on the fruit trees about 3 times per year.
Thanks for the info -I think I will be safe--- if it gets down lower than 28 then it won't only be the roses I will have a problem with. Thanks so much

Michael, that may be the most helpful number I've ever gotten - the 25/26 degree "breaking point". I've not read it anywhere, so thank you. My night temps occasionally break below 30 F, 27 F is about the lowest I remember. So, sounds like right now is a perfect time for me to prune. I really thought "frost" was the point which I had to be concerned with, and not prune when there is still danger of frost, which we can still get in late Feb.
