I don't know your entire set-up, Stevin, but if my husband wanted to store cuttings in my fridge, I'd friggin kill him! We do have a couple other refrigerators. One in the bar outside that we mainly use for Beer for BBQ's and a small one in our guest house. I'd sacrifice those, but with Christmas coming, and Thanksgiving (our big deal is on Saturday, so my fridge is packed......... and we have a vegetarian family member, so that's double cooking for me). NO ROOM in the fridge!
Is there some reason you can't just root cuttings now? They can be rooted all year, but if it's cold where you live, the garage might be cold enough for storage.
