grasa,
typically, i put about 3 cuttings into a bag. this time, i re-cut some of the cuttings to smaller pieces so some of the bags have 4-5 cuttings in them. the first 4 baggies already put out roots and i moved them into cups. i think, in that picture, there are about.. 40 cuttings of about 8 different types. Unknown Syrian/Turkish, St. Rita, Stella, MSVB, HC EL, Conadria Paradise Nursery, Persian White, and Ischia Green.
i read your post on "sweat chamber". the bags do similar things. even if they do not root in the bag, some will strike in the cup once moved. since i'm trying to slow down the process just a little to time it for night temp above at 50 in spring, i'm weiting for all of them to show some sign of roots before going to the cup. last spring, they stay at most 4 weeks in the bag before being moved to cup even if they do not show roots. about 80% of them turned into a tree.
