star jasmine propergation

Hi, I have a massive evergreen jasmine (8-10yrs old covers both sides of a 6foot fencing pannel) which I belive is star jasmine and is too big to move when we do (unless any one has a cunning plan). so the next best thing i thought would be cuttings but with no sucess. any help would be great.

Thanks

Heel cuttings usually take quite well. layering is also a good method of propagation for Jasmine, if you find any low shoots touching the soil you may find some of them have already started to root.
