Dear friends gave me a container rose bush about 1month ago but it is now Aug 17 and I have not yet planted it. It is a good size and rather hardy looking, and has produced about 7 robust blooms now finished. But it is getting a little big for the container. Our first frost will quite likely occur in a few weeks. Should I risk planting? I don't want to lose this lovely plant as it is special to me. Or is there a way to nurture and maintain it indoors for the winter? I live in northern Manitoba. Thank you.
