Taking cuttings from my old rose
My daughter started school in 1998 and we planted a beautiful climbing rose "Schoolgirl" at the side of our patio doors.
It has consistently flowered prolifically for all this time until 2017 when the number of flowers was significantly lower in number, their quality wasn't as high and, towards the end of the year, we had a lot of disease (typically blackspot).
I really don't want to lose this plant, for both emotional and aesthetic reasons, so have two questions:
What can I do to bring it back to life?
How do I take cuttings - just in case?
