Rick, the reason my Lilies are all potted up is because the place where I am living is a slight slope that had not been altered by humans: my intention is to alter it as little as possible (no machines to level, etc.) and my income is rather small. I want raised beds because of my bone pains and overweight, and because of rabbits I am thinking of a way to provide my future raised beds with some kind of chicken wire or so protecting my plants when i'm not out there. I will have to hire workers for this job (I'm saving money for this purpose!).
Don't worry, I will be very cautious using the fungicides - until now I thought I would never use them, but healthy Lilies are what I want.
