I root all my cuttings in water first. You get nubbins starting in a week or so if you keep them warm. Roots in 2 weeks. Don't change the water, as the cuttings themselves secrete their own rooting hormones.
Pot them up as soon as the roots are growing, so they will be stronger. (but I've kept them in water only for months, even had a cutting bloom in a vase of water, then potted and they took off).
Very easy, either way I think.
