Simon, if you have any willow trees (Salix anything) nearby you can make your own rooting hormone for cuttings.
Cut green twigs, not brown wood, strip off the leaves. Now cut the twig into 5cms pieces and in a container just cover them with boiled water. Like tea.
Leave to cool then add twice as much cold water then strain the twigs out. It will store for a couple of months in an airtight container.
By standing any cuttings in this the cuttings take up some of the brew which has growth hormone. (A coppiced willow wand will grow upto a metre a summer and cut willow happily roots in soil because of the high hormone levels in Salix). HTH
