I'm curious, topofthehill, why you are having problems with lilies blooming. Do you have enough sun, or is that the problem with getting them to bloom? If you have at least 4, preferably 6 hours of sunshine, they should bloom. Obviously, the more sun, the more blooms you will have. I have pretty much full sun, from sunup until late afternoon, so my lilies bloom very well. Another thing you might try is to fertilize them in the spring, when you divide the tubers (they usually need to be divided every year, if they grow well) and repot them. Also, if your pot is brought closer to the surface in the spring, they will begin growing sooner, then you can lower it if you keep them lower, once the leaves come to the surface. They will grow the leaves pretty much as far as necessary to get to the surface.
Also, maybe the type of lilies you have are not as hardy as some. I have several different types, if you want to try a new type, I could mail you one or more in the spring, when I divide mine. Just PM me. :blueflower: I have several plants that I originally got from Menards, but my favorites are ones that other ponders on this forum have shared with me. I am paying it forward, sharing with others now. Next year will be 3rd year I've shared. It's a matter of doing that, or tossing them.
