I have found that when you root a cutting in water that the hardest thing is
moving it into compost/soil/dirt.

I have found the best thing is to have a little dry peat, and dust the roots
with this first, so that each root is coated and they are not hanging as one
thick strand, it is then easier to get the roots to go into the pot
separately, this makes the move from water easier and less stressful for
the young plant.
When the roots have filled the pot then either pot on or plant out, and at
all stages water well, but don't over water.
