This is something I'm going to try this summer. You need semi mature material - grown that season but firmed up, not too sappy - use tip cuttings or leaf and bud, and use ericaceous compo mixed with a little grit. Put the cuttings in a propagator somewhere light but out of direct sun. Good luck!

I just took off a ' heel' and popped it in the ground and it took, mind you it has taken ten years to flower !!!!!!! Best to buy the real thing ! but still you get satisfaction from cuttings but boy do you have to be patient.
