Me too....but they will be losing leaves around now so don't worry. Are they little bulblets from seed or offsets? Depending on how big they are, you could dig them up and pot them out individually.....but if they are like mine, I will be leaving them for another year in clumps to grow on a bit more as they will not be reaching flowering size for at least 2 0r 3 more seasons. Lily bulbs are tough and easy as long as they soil is relatively well-drained.
I usually wait till spring when new top growth starts before moving them around - they are really obliging. Here is a first year minuscule bulbs from seed.

Thanks for your reply! They are offsets and were very small this spring when I planted them. They will stay in the containers over winter then. With all other yard work, it's just easier to leave them where they are. Thank you so much! Your little seedling is adorable!

So I was going to leave them in their containers but I was curious how much they had grown so I checked and found one of the containers was completely empty, only dirt. The other had bulbs in them. What could have happened to them? Did they maybe rot to nothing? This is very strange to me, especially because they other planter was fine.

mice?
Many creatures think lily bulbs are a delectable feast.
