You cut off about 10cm of this years growth in July and put that into potting mix. A coldframe would be useful too. They should root be September.

I may even try as have got 2 KM

If I did the same cuttings but for a Little Red Robin, would the new plants still be dwarf or would they revert into a full red robin??

@Sheilar - I would presume so as the parent plant is also a dwarf variety but would not guarantee it!
