I have had absolutely no luck in getting cuttings to root. More than 12 canes from 4 different roses of my own, and all of them turned to black and died. I've tried different levels of moistures, to water-only rooting, using various soil types. Nothing.
What has worked so far, however, is air layering. I know you mentioned it was a rose on a road, so this might be difficult for you. I took these pods from Amazon and filled it with coconut coir and followed the air layering technique (remove 1 inch section of outer bark, scraped off the inner cambium layer, then dusted the exposed area with rooting hormone. The entire area sealed by one of these pods).
It took 2-4 weeks, but the beginnings of the root nodes have developed on all 8 of my pods. Meanwhile, the section of the rose above the cut area is still thriving (some of them even sprouted new branches and flowers). I'll keep monitoring the progress, but at this rate it'll be a few months before any sort of root ball has formed. But so far, 8 out of 8 pods is a much better rate than my 0 out of 12!
i use this stuff to make a dig box for my boys, not for their cage though I put it in the playpen

its a bit of effort to rehydrate the dirt. put a layer of dirt down then sprinkle in some seeds then put some dirt over top, keep hydrated and takes about a week to sprout then I give it to them as they like to munch the freshly sprouted seeds
