I'm looking for some advice please? I've been given some tubers/bulbs from an established poeny rose bush, they were growing at the time so green leaves/stems but no flowers. I really want them to survive as kind of sentimental...what should I do with them? I have mainly pots in my garden, but am thinking of adding a small border in from garden. There is a small scrubby border which has been cleared next to a fence but its quite stony...bit unsure??
