Hello,
Any tips for successfully overwintering madonna lillies

Thanks in advance

I have tried to overwinter them in the ground here, and whilst they should
be fine, because they have some growth through the winter they get attacked
by lily beetle very early in the spring. They do seem to attract that pest
with their soft leaves.
Result is, after a couple of years with few leaves, they go downhill fast.

If you live in an area that does not have that pest you may well be OK.
