Question
I live in Michigan- zip code is 48141

How deep should I plant my cannas plants to avoid freezing? My neighbor does not dig up her plants but would not assist me with the above answer.

Answer
Love Thy Neighbor -- even when they not the friendly folks we wish they were.

I heard a comedian do some jokes once about his neighbor.  He pointed out that no one, not a spouse or a parent or a relative or a co-worker, can turn your life inside out the way a bad neighbor can.  And it was funny.  But so true.  So although you did not ask about this, I feel your pain, and I am hoping that the kindness will be catching.

Just between us, your Canna rhizomes should be planted lying horizontally, eye facing up (if you can see it).  Canna rhizomes have no top and no bottom; you can't plant them wrong.  The routine is 4 inches, but you can do 5 or 6 inches to be safe.  Cover with mulch for added protection.

They are quite hardy.  Specialists don't usually recommend you lift them unless Winters hit 10 degrees below zero.  I know it's cold in Michigan, but I don't think it's THAT cold.

If you Cannas are planted near a foundation (within a few feet), fairly protected, you will benefit from warming of the Soil through winter, especially if the exposure is Southern.

Of course, you must not fertilize these right now.

Thanks for your question.
