I wait till there is a good root system. Then water with a B1 solution. Water the pot or ground they are to be transplanted to with a B1 solution and or a root growth stimulant. Tamp gently but firmly making sure there are no air pockets. Water again if not throughtly watered. Keep them protected from strong heat, cold, or wind for a few days. I don't find it much different than transplanting other plants. Easy does it.
