Thanks for that info, I would rather wait until autumn but if they come up the same as last year the plant above ground will be quite substantial by then. I don’t know how well that would transplant. I’m surprised these bulbs come up at this time of year considering they don’t flower until Christmas.

Actually once they have flowered the stems can be cut and the bulbs transplanted at that point. If they are tiger lilies as you suggest then the bulbs can be broken into pieces that will all grow.
