Is the area to be planted stream-side or riparian? On drier sites you may want to root the cuttings before out planting them. For riparian areas where moisture will be available, cuttings alone can work well.
Typically cuttings are taken in late winter, so you may want to wait to do this. You'll want to start with 1 year old stem growth (older material will not be as vigorous) for your cuttings. The straighter the better. Make sure the cuttings each have at least 3 viable buds but don't use end buds. Diameters shoudl be about 1/2 inch. You can use long lengths of about 3 feet if the soils will allow you to push the cutting down that far. You can plant the same day as you make the cuttings. Push each cutting into the ground as deep as possible, leaving only the upper most bud above ground. If you can't plant right away, use cold storage and then plant them early spring. Treatments with indolebutyric acid can improve rooting.
If you want to root them first try a medium of peat - perlite - vermiculite.
