Easy to do Paul - that's how I've got all mine :) From the Botany site:-
Cuttings that are made from half-ripe or semi-woody side shoots, 5 or 6 inches long, can be inserted in a closed cold frame, or outside under a hand light in July or early August. Cuttings that are made from the mature shoots of the year, 12-18 inches long, are taken off with a thin "heel" of the old wood at the base and inserted in a sheltered border outside or in a frame in late September or October.
So, old wood at the base with a 'heel' for you, then.
Hope this helps, Lishka
