Certainly leave them in the ground until the foliage has finished doing its stuff and died back naturally, otherwise you won't have properly developed bulbs for next year. They don't like heavy wet soil when dormant, so dig them up if you are on clay or badly drained soil. I'm on heavy clay and have tried leaving them in the ground over winter (because I'm lazy) and it doesn't work - they might come back once, but never again. I love lilies, so grow them all in large pots, which I keep on a bench at the end of the garden so that they are well drained over the winter. Then as each pot is about to flower I get my OH to carry it into situ in the garden. So I can have a succession of blooms without having to keep digging up and re-planting. I do have to take care of them in the pots - weeding, top-dressing and feeding the pots, and changing the compost every few years, but some have lasted me for years like that. Some just fade away, whatever I do, so I suspect some varieties are stronger than others. For the tree lilies, I've planted two lots in pots (18" for 3 bulbs as instructed, which is huge!) and one lot in the garden in a raised area with loads of grit. Only time will tell which will do better. Big Susan
