Pat, this one can be rather difficult. Might I suggest a hybrid of it called Kushi Mayo. It is a lot easier to grow in the garden. Their suggestion that pots be buried sideways would apply to ALL potted lilies, regardless of what kind and type. The reason is the drain holes freeze up in the winter preventing drainages; the pot collects water which can't escape, effectively drowning the bulb at some point. Here's pictures of Kushi Mayo, the hybrid I suggested. You can buy it from The Lily Nook here:
