I have successfully rooted some fig cuttings using a bag method where one wrapes the cuttings in moist paper and place these in a Ziploc plastic bag and then place it in a warm place at 25C~27C environment and one can observe root initials and then roots in 3~6 weeks. Afterwards the cuttings are potted. Has anyone used this method for rooting grape cuttings successfully for initializing roots?
