I think that soaking them in ice is a great idea! Wish I knew that before this thread, but could come in useful in the future. Soaking wilted lettuce in ice water brings it right back to life, so probably would work on wilted cuttings too!
You do have a point about mom worrying about cutting fruiting branches. I was very careful not to take my 20 Catherine's Nacido, and 20 "Wild One," mystery fig cuttings from fruiting branches. Most came from suckers at the bottom of the tree, and those suckers will simply branch and keep on growing.
It's been a week since mine all got stuck in 4 2 gallon nursery pots, and I know in a month or two I'll have to separate them all and re-pot the survivors in their own nursery pots.
Fingers crossed that yours grow Jo-Ann!
