We are moving soonish and I would like to take a cutting (?) of my enormous climbing rose with me. I can trace this plant back several generations and it all started with my several times over great grandmother so it’s important I get at least one viable plant off of this. Any advice on what time of year, where to cut, anything would be so helpful. Yes, I’ve googled, but the advice there is so conflicting.
