Hi there!
I personally would have skipped the 'rooting in water' thing and gone straight to potting them in soil. BUT.... too late for that now, so get on with the potting up in soil:-)

I've add a link to rachels with should explain everything you need to know to do this. Hope it helps!

Once you get it potted don't forget to put it in a plastic bag (blow air in and seal it) for a couple weeks to let it settle in with less stress!
