I've rooted cuttings that have been in the fridge for more than 8 weeks with no water change or maintenance of any kind. Some people make sure they have several cuttings from each of their valued mothers in the fridge at all times as an insurance policy. Just make sure that they're not in the back corner that freezes, but the colder the better.

I'm not saying 8 weeks is ideal, but a few is no problem. The longer they stay in the fridge the less success you will have. Less than 1/4 of the old ones rooted for me, and they were near rotting when I decided to root them. Aint weed amazing?
