From what I learned last week, one of the most important things is the weather unless you have a controlled environment to keep them in. They have to be completely dry and kept at a certain temperature when they first start growing after being treated. If the temps and humidity get to high there's a good chance they will not survive. There are so many things that can go wrong when doing this, many daylilies have been killed during this process, including several of my own, but its the only way to get the dip genes into the tets.
