Hi,
Try this for me : put cotton (the white fluffy stuff to clean wounds ) around the cuttings and wet it.
Put it in the dirt in a shady spot and keep it watered - the soil should be wet/fresh but not damp .
Of course, remove all but the last two leaves on the cutting and burrow it till 3/4 of total length . I had good luck with some bushes propagating them like that.
