Taking Rose cuttings

[CaveMum]

We are moving house next week and I want to take some cuttings from a very old and beautiful rose in the garden of the house we are leaving.

I've bought some rooting powder and have seen a few bits online advising to take cuttings of fresh (this year's) growth of about 25cm, but I'm wondering if anyone has any additional advice?
I'm planning on taking 3 or 4 cuttings, just in case a few don't take.

All help and advice much appreciated!

I have seen my DF do this many times as a child. He would cut the rose stem diagonally, spit on it and them dip it into rooting powder and plant in a disposable coffee cup.

Many thanks!

Do I have to use a specific type of compost to plant the cuttings, or is generic compost ok?

My technique is to take a lively looking piece of the rose, remove the lower side-shoots, rough up the rooting end a little and then suspend in a narrow-necked bottle with some water. When tiny roots appear, transfer to a pot of all-purpose compost and keep damp. Take plenty of cuttings as some will fail.

Caveat.... some roses are grafted onto vigorous root-stock and cuttings from the flowering end of the plant will not be quite so lively as the original.
