I have a few lilies that just aren't in a good place. When is a good time to move them? I am zone 8b and hot and humid right now. Cool fall weather usually doesn't start until late November.

Hi Sallysmom: You don't say what state you're in region wise, but when you say 8b and it's hot and humid, I'll guess your in the Southern or Southeastern states. In that case the best time to transplant them would be anytime from late October through early December. For those living in cooler zones of 6b and lower, they can be moved as a clump without disturbing the roots, preferably immediately after blooming. But in the far Southern and Southeastern US it stays too hot too long and it's best to wait till later. Mark them now and don't forget to 'water them in well' once after transplanting.

You will have all winter to move them but do it before they start to grow in the spring or you risk damaged buds.

What about zone 4B? Can I just dig and separate the bulbs after the foliage dies down? This is what I do with my common lilies, but I hesitate to do it with my rarer ones.

Sure, that would be the best time! In zone 4b, that would most likely occur in early October.
